I've entered a question yesterday and Meta StackOverflow says it was submitted 22 hours ago, and it's 15:00 on my local time, however Meta StackOverflow says the question has been asked today.

Any time you see in the system is not localized to your time zone, so the time when a new day starts according to the site may not necessarily be the same as when a new day starts for you.

As it says on your recent activity page (click the envelope at the top), all times listed are in UTC.

  • So Stackoverflow can't say to me that the question has been asked today because saying that way is a localized answer. Apr 28, 2010 at 18:14

    It HAS been asked today. It's not SO's fault that you use crazy moon time.

    @mmyers: 23/24ths of the planet are part of the Moon?

  • Have more pity for the poor guy in Tonga (near the international dateline, UTC+13) Apr 28, 2010 at 18:40
  • @Andrew, thank you for pointing me to that, I didn't know that UTC+13 even existed!

  • It's actually not that strange once you get used to it. We use UTC on all production systems here at my $work, which makes time calculations so much simpler, so I've gotten quite accustomed to keeping time in both UTC and my local timezone. I have even started to think of 5pm (or 4pm in the winter) as "tomorrow". :)

  • I've never found it to be a problem until you travel, in which case I keep my watch and laptop clocks on UTC, and just start thinking about lunchtime as dinner, dinner as sleeptime, sleeptime as breakfast and breakfast as lunch Apr 29, 2010 at 11:07
  • Lol I'm at GMT -3 Apr 29, 2010 at 13:45
  • @Gabriel: SO am I.
