Windows Mail gets the time data from the message, and then translates
it to your time by comparing the time zones. In order for this to work
properly, both your time zone setting and your daylight saving time setting
have to be set correctly on your PC.
It is quite possible for your PC clock to show the correct local time,
but still have its time zone setting incorrect. If the time stamps on
incoming emails are all incorrect by one or more whole hours, that
is almost always the result of your PC's time zone setting being incorrect.
My incoming mail is always 3 hours behind my correct time as I set it on the
computer. How do I fix incoming mail clock? I'm on Eastern Standard Time in
Canada.
I can't tell what your time zone setting is since you posted through the
web interface. My guess is that your PC is configured for the Pacific
time zone. To correct it, right-click on the time display, Adjust Date/Time,
Change time zone.
