I have to completely disagree.

In my experience, people's idea of what timezone they are in is
frequently wrong, even quite well educated people. Last year I had to
explain to a Harvard Law student when the US time changed that EST and
EDT are different, and the only reliable way to tell students from
Asia what time an online class starts is to give them the UTC time.

Here in the IETF we are spread across at least ten time zones that have at least three
different schedules for summer/winter time, along with several more that keep the same
time all year.  The only reliable way to tell us all when something happens is to tell
us in UTC.

R's,
