Mini-HOWTO: What Time is UTC?

I wanted to know what time it was in UTC, but I forgot my local offset. (It changes twice a year!) I figured I could look in the date man page, but I came up with an “easier” solution. Simply fudge the time zone and then ask.

0-20:57 djh@noneedto ~$ env TZ=UTC date
Tue May  6 03:57:07 UTC 2008

The env bit is not needed in bash, but it makes tcsh happy.

Update: Mark points out an easier solution:
date -u

Knowing you can set TZ= is still useful in case you ever need to contemplate an alternate timezone.

(Thanks, Saul and Dave for improving my knowledge.)
