The difference between "20 minutes ago" and "5 hours and 20 minutes
ago" doesn't really come up when your resolution is 86400 seconds, as
is the case with a date :)

I have the same sort of thing. My desktop's clock is on local time
(4:33AM), but my server tells me, when I type 'who', that "The current
UTC (GMT) time is: Wed 17:33:35" (it doesn't bother with the date,
only the day of week, as the main purpose of that time display is to
help people synchronize on weekly events).
