The traditional solution is to get your time by radio from https://en.wikipedia.org/wiki/DCF77 https://en.wikipedia.org/wiki/DCF77 or your regional equivalent. It might take up to 24 hours to update but it will always be correct and requires no manual interaction whatsoever.
- fsckboy 3y ago> It might take up to 24 hours to update but it will always be correct sounds like it might be incorrect only(!) for 24 hours at a time, with "how many times" being the wildcard.
- scraptor 3y agoIt will be incorrect whenever the time changes, so twice a year and maybe once more if you expect your microwave to adjust for leap seconds. Depending on the device it will also lose track of time if it looses power but in that case it should know to resync immediately.

- felipeerias 3y agoJapan uses a similar system: https://en.wikipedia.org/wiki/JJY https://en.wikipedia.org/wiki/JJY Most typical home clocks will use this signal to set themselves up automatically, which is made easier by the fact that Japan does not have daylight saving time.
