that the minute after 2359 UTC on November 2 (i.e., 7 hours after the

November 3?
I've seen it used both ways so I just want to be clear.
Could you elaborate on this confusion and where you think it is common?
The 24 hour clock divides a day into 24 hours from 0 to 23 starting at
midnight. 23:59 is 23 hours and 59 minutes after 00:00 on the same day.

The minute after 2013-11-03T23:59Z is on November 4th. I do understand
that when setting a deadline you are better off giving the end of a day
as deadline so the time is up when the day is over, otherwise people see
a contradiction and get confused, but beyond that I've not encountered
this particular confusion.

Bjoern, it might just be that I am old and remember the ancient days when
the 24-hour clock was first coming into use outside of the military; it was
common back then to see a time like 00:01 written as 24:01. The fact that
we have a date change creates the mental expectation that there will be a
day's end before the next meeting, but for people in North America, this is
early afternoon vs late afternoon/early evening.
But yeah....I just asked a simple question, and I've got a nice answer.
I've also got a fair amount of slogging. Let's end this thread now, okay?
