Alright, now for today’s problem: why do two dates that look different when outputted actually end up being the same date?
Answer: I’m not sure, but I’m pretty sure it’s got something to do with the wacky support the above-mentioned 3 products have for timezones.
The background: Plone stores a DateTime object to record a user’s last login time. It doesn’t really matter what’s purpose is, because Plone (this time) isn’t at fault. The DateTime gets stored, no worries. The problem arises when you try to put that value back into a DateTime object. Now, I’d have thought it’d be as simple as doing this:
dt = DateTime(member.getProperty('login_time'))[/sourcecode]
And realistically, it is. Except that printing/using that value - at least for me - results in a time that appears as UTC, but is reported as being in my timezone (aka a time that’s 10 hours behind since I’m GMT+10).
The fix: the time still knows its timezone correctly, so just give it a kick:
dt = DateTime(member.getProperty('login_time')) dt = dt.toZone(dt.timezone())
Amazingly, doing a comparison (using cmp) between the original DateTime object and it’s ‘corrected’ version actually shows that they’re the same. Uhuh.
