Actually because of daylight saving times and all the timezones that

YYYY-MM-DDTZD as the W3C & ISO propose

Only when the time needs to be specified at all :-) If the information
I'm giving can be off by 24h without consequence, adding the time is
just a waste of keystrokes. Especially when the margin of error is of 12
hours anyways.
Adding timezone means people in another country will be able to convert
if needed. Adding explicit timezone (time differential with UTC) means
if you're in a country that does DST the day it happens you know if
you're before of after the switching point.
When I post a time that is relevant for an international audience (e.g.
the time of an IRC meeting) I post it in UTC.
In my country for example railroad control systems were developed using
local date/time reference. As a result they have to stop every single
train in the country one hour every year, because this hour does not
exist for the control systems and it would be dangerous to let trains
move.
That's really funny.
Cheers,
Daniel.
