- nicktelford 8y agoKinda weird mixing a European timezone with an American date format. Parent means 2019-03-02T07:48Z
- jessriedel 8y agoNot that weird I think? Americans are a plurality and probably majority of HN commenters, and UTC is a universal time zone (hence the "U"). American astronomers would describe observations in UTC (with the American time format), regardless of the timezone the observation took place in, yet would still communicate between themselves using the American date format. (In contrast, it would indeed be weird if the European time format with the colon was intermixed with American date format, e.g., 1130 UTC on 3/4 for 11:30am on March 4th.) That said, HN is sufficiently international that mentioning the date format to avoid confusion is good.
- SiempreViernes 8y agoI guess amateur astronomers might use something else besides UTC or some form of Julian date to label their data, and the professionals might well put whatever date format they well choose in their directory names. But looking at the Keck open data archive or the time conversion utility NASA hosts I found little evidence they frequently use anything else than standard iso dates.
- jessriedel 8y agoIt would make sense that Keck open data would use the international ISO standard, no? Further, NASA changed (in 1990) to the metric system, but this doesn't really change how two American astronomers would communicate with each other on a day-to-day basis.
- SiempreViernes 8y agoIt'd be pretty weird for american Astronomers to use a strange date format for their observations, but not strange if they used them when talking about their next seminar.
- alistairSH 8y agoCurious, do any nations outside the US use M/D/YYYY? Silly anecdote: I have family in Scotland. Prior to getting married, we sent "save the date" cards to them. The listed date was "6/3/06" (June 3) and they were sent in February. Of course, first response from an uncle: "Well, you didn't give us much heads-up. Is she 7 months pregnant?"
- saiya-jin 8y agothat's why you always write name of the month in dates
- jstanley 8y agoUTC isn't a European timezone, it's "universal coordinated time".
- anarcticpuffin 8y agoThis is why it's good practice to just never use MM/DD or DD/MM dates anywhere. 2-Mar or 2-MAR is nearly as terse but much less ambiguous. The only other date format I default to is YYYY-MM-DD (i.e. 2019-03-02). It sorts well and, by putting the year first, doesn't pick a side in the MM/DD or DD/MM battle. It just lists the terms in descending significance.
- weavie 8y agoSo much of my life has been wasted because people want their dates formatted dd/mm/yyyy in their browser..
- konschubert 8y agoUse Moment.js
- mattashii 8y agoFormatting, sure, but inputs... One of our customer integrations uses all of MM-DD-YY, YY-MM-DD and DD-MM-YY for a date input. Took us quite a few man-hours to figure out why our integration layer failed so often.
- cmroanirgo 8y agoSo much of my life has been wasted because people want their dates formatted mm/dd/yyyy in their browser.. ;-)
- magnamerc 8y agoI'm an engineer in the aviation industry and I stick exclusively to DD-MMM-YY (26-Feb-19). Too many different formats used globally.
- randallsquared 8y agoUnless you use four digits for the year all the time, it will remain ambiguous.
- 8y ago
- Whatevers 8y agoUTC isn't even a timezone.
- rory096 8y agoYeah that's a fair point. I actually originally had "Saturday at 07:48 UTC" and realized a few hours later it might be helpful to have a date in there... at which point I'd lost the ISO-8601 context in my head.
