help time

time
time <who>
time <number>

This shows the current time. Times are shown either in UK time or your local time if you have set it. If you are in a timezone other than the UK, you'll be shown the server time, too.

If you want to see someone else's timezone, and the time it is there, specify their name.

If you want to look up a numeric timestamp (Unix epoch time), supply the number to look up.
