Time.is
- aravindc 15y agoThis is exactly what I wanted. I used to google everytime to find time. Not anymore, and it looks cool too.
- wilfra 15y agoSame, Google just lost a few searches a week from me :)
- riobard 15y agoI still like this one instead: http://everytimezone.com/ http://everytimezone.com/
- Shtirlic 15y agoWhite on black is perfect.
- Tobu 15y agoI'd prefer the logo to be a bit more subdued over the relaxing black background.
- mtr 15y agoShows incorrect time for Chile. DST isn't until April 28th. http://www.timeanddate.com/news/time/chile-longer-dst-2012.html http://www.timeanddate.com/news/time/chile-longer-dst-2012.h...
- apaprocki 15y agoIt means that they didn't apply the latest tzdata2012a or b update released the first week of March which contained the America/Santiago zone change.
- phillmv 15y agoTime is a surprisingly difficult subject to get right.
- apaprocki 15y agoGovernments are free to change timezone rules at will with no real advance notice. Case-in-point, tzdata2012b was just published a few days ago and already on the tz mailing list Morocco's DST date is changing and Haiti apparently changed as well. The problem is exacerbated by the fact that most systems rely on OS tzdata instead of shipping it themselves, yet in many places the administration of the OS is separated / walled off from the devs who maintain the apps which actually suffer from the bugs. I feel bad for users who live in countries whose governments play with DST law on a whim, because they are certainly destined to encounter bugs throughout the Internet because it isn't always reasonable to ask all administrators around the globe to patch all production systems in a matter of a few days.
- time_is 15y agoThanks, we have corrected this now. :)
- bbx 15y agoExactly what I needed. For the last few weeks, I've been trying to increase my productivity by getting rid of time tracking. So I decided to hide my computer's clock. Sometimes, like when I have an appointment, I still need to check what time it is. Googling "time" doesn't always work (I don't know why exactly). So I bookmarked this site [1] but the information density is so high that I need to scan the page in order to get the time. Time.is works quite well, with useful customization options, though it still carries bits of useless information (like the time zones at the bottom). But the time's font size is big enough to trigger instant focus. UPDATE: as guptaneil pointed out, clicking the time (or navigating to http://time.is/just http://time.is/just) removes all the clutter. Thanks for the tip.

- mrud 15y agoI really like http://worldtimebuddy.com/ http://worldtimebuddy.com/ as it allows you to see time zone differences without the need to calculate it yourself.
- djsla 15y agoIt does not do clock sync/accuracy determination. Time.is is rather unique that way. However, I'm skeptical over the importance of that feature. disclosure: worldtimebuddy founder.
- aeden 15y agoNice job on this. I usually use http://everytimezone.com http://everytimezone.com but I like how I can configure this with the zones that matter to me. It would be nice if I could easily use my favorites when doing the Here -> There comparison.
- zarroba 15y agoI would still prefer to have the option to select the timezone. Sometimes I want to attend some workshops that announce the time in one of the US timezones and its always difficult to do the conversion.
- napoleoncomplex 15y agoWhat would be ideal in this case is a browser add-on or a bookmarklet that enables dynamic conversion. The add-on would be simpler, as a text-select and right click could show the selected time in your own time zone in the right-click menu. It's something I've missed every single time some press conference or event is announced, and it just says 12:00 EST.
- darklajid 15y agoThat would be, as someone else mentioned in this thread, worldtimebuddy. I use it for exactly that purpose and consider it gorgeous.
- acerimmer 15y agoAnother very nice web for timezones is http://tmzns.com http://tmzns.com.
- sabatier 15y agoThis is gorgeous.
- mwexler 15y agoI like Time.gov, personally; it was the first site I ever found around this concept and so it has a soft spot. I keep finding all my physical atomic clock synced clocks (yes, I have more than one, they are cheap these days) disagreeing, sometimes by 2 seconds or more, which makes me laugh (great ideas ruined by poor implementation). I find many of the web sites (listed in comments or the original post) to also differ, perhaps for similar reasons of implementation choices. I would presume all the sites work off various implementations of NTP, http://www.ntp.org/ http://www.ntp.org/ plus some trusted source. I guess my question is: has anyone found a site which is really, really accurate by reducing all the latency and lag, so what you see on the screen really is, to whatever precision, accurate? And would said person have access to a really good source for the comparison point? I don't seem to have one. Yes, I should have stopped at 3 so that I could pick the 2 closest ones (like the old saying: 1 clock is unsure, 2 clocks are worse, but 3 at least lets you make a decision) I wonder, would you need to have NTP on the client side synced to a trusted source (say, in java, flash, or javascript) to get a good reading? Any server serving over HTTP induces lag, I would think, and NTP is supposed to account for transmission delays, or so I recall. Thanks for sharing, another interesting time site to add to the collection.
- ken 15y agoWhen I was a kid, my dad would always set our clocks by tuning the radio to one of the atomic clock broadcasts from Fort Collins. This might be the same source as your automatically synchronized clocks, but the advantage is that it's human-listenable, and not going through any computer networks or algorithms between Colorado and you. https://en.wikipedia.org/wiki/Radio_clock#List_of_radio_time_signal_stations https://en.wikipedia.org/wiki/Radio_clock#List_of_radio_time...
- dfc 15y ago"The advantage is that it's human-listenable, and not going through any computer networks or algorithms between Colorado and you." That is an advantage? The Fort Collins signal is awful in the northeast. If you want to deal with the disadvantages of not using advanced computer algorithms to govern your clock i would recommend the USNO's phone service: Time Voice Announcer, Washington, DC: 202-762-1401 & 202-762-1069 (DSN 762-1401, 762-1069) Time Voice Announcer, Colorado Springs, CO: 719-567-6742 (DSN 560-6742)
- sylvinus 15y agoNice, however on my Chrome Mac there's a flash each second with the re-render.
- ynniv 15y agoWhen clicking the time in FF 10.0.2, everything disappears expect the Google +1.
- libria 15y agoOP, what does this line do? if (wn == 1) pwn = '1-ին շաբաթ'; It looked like something related to week number; looks interesting.
- sushimako 15y agoGoogle Translate says it's Armenian and means "1st week"
- Aramgutang 15y agoIn a fuller context: if(p_wn=='hy'){if(wn==1)pwn='1-ին շաբաթ';else pwn=wn+'-րդ շաբաթ'} So if the locale is "hy" (Armenian), and the week number is one, set the string to "1st week", else set the string to "#th week" (both in Armenian). Unlike English, which also has exceptions for "2nd" and "3rd", Armenian only uses a different suffix for "1st".
- silentscope 15y agoclever url folks.
- silentscope 15y agoI wasn't being sarcastic guys. I meant that, it's pretty clever.
- eropple 15y agoYou weren't downvoted for being sarcastic. You were downvoted for adding nothing to the discussion.
- tibbon 15y agoSimple, but awesome. About two years ago I had the idea (but never implemented) to try and re-make various since use web tools and calculators using modern web technology. Things like interest/mortgage calculators, voltage drop calculators, difference between two dates, etc. So many of them like Time.gov rely on stuff like Flash or Java, or 1998 style Javascript, which I don't really dig. Definitely a nice little hole there for making something cool.
- hrktb 15y agoThe handling of internationalization is surprisingly good. Texts, including town names, are almost all shown in the preferred language, and the size variations introduced by the translations are well handled.
- mdda 15y agoFor those alarmed at the offset... # yum install ntpdate # ntpdate -u ntp-1.vt.edu # hwclock -w "Your time is exact!"
- morsch 15y agoThis is an unobtrusive app that does the job for Android (root required/recommended): https://play.google.com/store/apps/details?id=ru.org.amip.ClockSync&hl=en https://play.google.com/store/apps/details?id=ru.org.amip.Cl... My ZTE Blade/CM7 was obnoxiously bad at keeping time, probably a software bug or something.
- justincormack 15y agoNot sure why Android does not have ntp built in. My network does not broadcast a time signal, maybe it is just assumed they all do.
- dfc 15y agoYour cell network or you do not have multicast ntp enabled?
- justincormack 15y agoCell network doesnt broadcast time. You can install ntp client, but it needs to run as root, and I wont let anything from the market run as root, and I havent got around to building an ntp client myself...
- dfc 15y agontpdate is dead and is discontinued. Use an actual daemon to govern your time source. I thought redhat installed ntpd or chrony by default. I know chrony is the default for the next fedora release. If you have ntpd/chronyd installed your advice is horrible and not just because you pointed everyone to Virginia Tech's time server.

- guylhem 15y agoI like it a lot. Easy to remember URL. However the services offered are not so good. At least there is no RFC 867 and RFC 868 date on port 37 and port 13. This is deprecated, I know, but rdate is still the easiest way to fix the date on a system which do not require precision. I did run my own minimal daemon on my DSL modem for the various gizmos I have that include busybox (thus rdate) and where recompiling to get a ntp would be overkill. (the right day and the right hour are more than enough) time.nist.gov removed RFC 867 (port 13) and 868 (port 27) support. time-nw.nist.gov kept it a bit longer, then I used by DSL modem, which went in RMA and so guylhem.org is also down. I'll try to email the author and offer to give a hand.
- dfc 15y agordate is awful that is why NIST killed it. If you want a fire and forget time check: sntp pool.ntp.org
- guylhem 15y agoI know rdate is awful but when that's all you have and don't feel like crosscompiling for a device which does not even requires a minute of precision, it does the job. Technical excellence is not always required, and having more choices usually is a good idea.
- gwern 15y agoYour clock is 0.2 seconds slow. Accuracy of synchronization was ±0.625 seconds If the result is within the margin of error, wouldn't it be better to just not tell me at all?
- dfc 15y agoI imagine that the author of the page has some scientific background and therefore feels that it is appropriate to publish the margin of error alongside any estimation.
- moe 15y agoReminds me of the radio clock that I have in the bathroom. It is labeled "DCF signal - precision time", yet is off by hours most of the time (jumps randomly). I keep it for the entertainment value. Guests always have a good chuckle when they enter the bathroom at 16:41 and leave it at 23:41.
- ilaksh 15y agoWow.. that's a new one. Now I have to buy an .is domain.
- TazeTSchnitzel 15y agowhat.is? love.is? it.is?
- roryokane 15y agoI'm wondering how atomic clocks in general get set in the first place. Did, at some point, scientists calculate when the sun was exactly overhead Greenwich and call that noon? Because I would think that that calculation would have a multi-second error, so setting your clock to the second would be pointless. Or maybe there is no such thing as "actual physical time" and there is only what people have agreed to call the standard. But in that case why do time sources, such as time.gov and time.windows.com, still give different times? I would think Microsoft would have fixed any bugs in their NTP implementation by now, so it's not that. If it's just politics about nobody wanting to move to someone else's time, then there's no way to tell which source is the real standard, so your most practical choice is to synchronize your clock to the times you deal with. That is, set your clock to your clock at work, or an average of your friends clocks, or whatever source they get their time from. I don't mind the existence of central time sources, because they are better than having to go out and find someone else's clock, but they shouldn't call themselves official if they aren't actually official. So, does anybody know how the starting time for central time sources is chosen, and if any source is worthy of being called "the real time"?
- dfc 15y agoUTC is a "paper clock." The calculation of UTC has nanosecond error, not multisecond error. The most recent data for the calculation of UTC: ftp://ftp2.bipm.org/pub/tai/publication/cirt.290 Time is a really tricky and interesting topic. I would start with: "From Sundials to Atomic Clocks: Understanding Time and Frequency" http://www.nist.gov/timefreq/general/pdf/1796.pdf http://www.nist.gov/timefreq/general/pdf/1796.pdf "Originally published in 1977, this full-length book provides a comprehensive, easy-to-understand introduction to the field of time and frequency. Readers of nearly all ages and educational backgrounds should find it enjoyable. 306 pages."
- phillmv 15y agoWell… it's an arbitrary standard. We just call a day one full rotation of the earth, and we just happen to divide it into 24hr periods with 60 subdivisions. Theoretically, you could measure the rotation of the earth and call that a day, but I have no idea how you would measure that down to the millisecond. As to "Real Time", I don't know about the specific legalities, but the standard goes as follows: everyone uses UTC http://en.wikipedia.org/wiki/Coordinated_Universal_Time http://en.wikipedia.org/wiki/Coordinated_Universal_Time which is based off the International Atomic Time http://en.wikipedia.org/wiki/International_Atomic_Time http://en.wikipedia.org/wiki/International_Atomic_Time I too would be interested in how they picked the beginning epoch, i.e. "this moment right here is midnight from which all other seconds shall be referenced against" but in the grand scheme of things it doesn't matter - the only thing that matters is the standard we agreed to measure against.
- dfc 15y agoA lot of people are making disparaging comments about the acccuracy of the site's time estimation with little or no explanation/data. All things considered (three samples to estimate clock deltas and network delay) the time estimation is fairly accurate. time.is reports my clock is: -0.004 seconds (±0.021 seconds). I have a stratum one time source on the local network (gps+pps) and my ntptime agrees with the time.is estimation: dfc@bushido:~$ ntptime ntp_gettime() returns code 0 (OK) time d3077752.4160a634 Sun, Mar 11 2012 15:11:14.255, (.255381196), maximum error 260579 us, estimated error 3294 us, TAI offset 34 ntp_adjtime() returns code 0 (OK) modes 0x0 (), offset -4842.630 us, frequency 8.446 ppm, interval 1 s, maximum error 260579 us, estimated error 3294 us, status 0x6001 (PLL,NANO,MODE), time constant 10, precision 0.001 us, tolerance 500 ppm, NB: this is my laptop. so powersaving, heat fluctuations are adding a decent amount of uncertainty from a metrological standpoint.
- 7952 15y agoIt would be good if you could make the title of the tab show the time.
- MattRogish 15y agoCool site! QR code on the "About" page is a head-scratcher, though.. http://time.is/about http://time.is/about
- jarek 15y agoThe idea is you can scan it with your phone and not have to type the URL in. Not sure how many people actually do that though.
- MattRogish 15y agoA) If you're viewing on your phone, it's mobile optimized B) If you're viewing it on your desktop, why would you want to go to your phone? C) Time.is has to be the easiest URL to enter by hand in a device browser. :D
- jarek 15y agoI'm not saying it's very useful, but if you see it on your desktop and want to check it or save it on your phone (to verify the time on your phone/QR-and-web-enabled mobile device, to bookmark it for future reference when on the go, etc), the code might help. I've seen this used better than just on an 'about' page, though.
- samt 15y agoTell me I'm not the first to see the irony of a page full of comments debating ntp, GPS and atomic clocks, while there are two interesting front page stories about the value of ambitious goals.

- iag 15y agoI am seeing roughly +/- 0.1s accuracy range on my browser. Can someone please enlighten me on why we cannot reduce this further? I assume this page has <100ms response time, can't they get to a better accuracy range?

- cynwoody 15y agoVery nice! My little Ubuntu machine is -0.018 seconds (±0.009 seconds). My MBP is -0.012 seconds (±0.021 seconds). I recommend you add a percentile score of exactness, along with breakdowns based on platform, and suggestions about what to do if the percentile is disappointing.
- chanux 15y agoSimple and amazing. I used a simple shell script to query timezone info to find world time in CLI https://gist.github.com/2020097 https://gist.github.com/2020097
- treelovinhippie 15y agoAny idea what geolocation method they're using here? It got my city spot-on when usual IP geolocators put me elsewhere.
- ideaoverload 15y agoThe clock display is nice but not a killer for me. Here&There time comparison in different time zones is the best I have seen. Full page calendar with multiple months is very simple but works great for me. This is becomes my favorite site for time/date related stuff.
