That's when I started wondering how many different time/date standards there really are. http://en.wikipedia.org/wiki/Time_standard is a good starting point, but is sorely lacking in the various formats used by e.g. Unix, Windows, TRS-80, etc. And that is without even getting into the various calendars that have been in and out of use throughout the ages.
So how about it Slashdotters? How many different time/date "standards" can we come up with, and I'm betting there are more than a few horror stories of having to translate between them..."
