Timezones

I just subscribed to the newsgroup "rec.humor.oracle" which Google dutifully e-mails to me so I don't have to remember to go check it.

Sometimes it's worth it:

The Internet Oracle has pondered your question deeply.
Your question was:

> My friend has a dell optiplex with XP. She doesn't use it but
> I use it when I visit every week (in fact I am typing this
> question to you from that very machine at this moment!).
> Anywho, every week the clock is off by 3 hours. Why is this?
> It can't be a battery or something like that since the
> minutes are exactly correct (as is the date). Only the hour
> is wrong. What's up with that?

And in response, thus spake the Oracle:

} Your friend is clearly in the wrong timezone. She should probably pack
} up her belongings and move East/West about 3000 miles (depending on
} whether the clock is 3 hours fast or slow).
}
} You owe the Oracle a grovel-producing algorithm written in Visual
} Basic.
