Ever get an email? Mine looks like this:

My email client tells me that you sent your email about lunch time
wherever it is that you are, which tells me more than 5am my time. 
For instance, it tells me I'm not likely to get a response at 6pm my
time.

The above timestamp is (local time, offset from UTC) vs Mercurial's (UTC
time, offset from UTC), which means doing absolute comparisons is
slightly easier with Mercurial.
