]Got me there. Before googling, I'd never heard of UTC. I am guessing it is
]some equivalent to GMT? My hardware clock, IIRC, is set to Pacific Time.
Universal Time Coordinate. It is the world's atomic time corrected for
various relativisitic effects and referenced to the center of the earth.
GMT, like PST is just one of the time zones on the earth, defined in terms
of UTC. (It happens to have zero offset with respect to UTC , excpet a
slightly faster rate than atomic time because of the earth's rotation, which depends on
lattitude.)

]Um, so I need to change Windows to this "UTC" thing? Okay, I'll look it up.
You may not be able to. Windows decided long ago that the hardware clock
should show local time with all its foibles. This means that the hardware
clock has to be changed twice a year. Linux decided that jobs like that
were best left to the computer itself, so the hardware clock remains fixed
and the computer corrects to local time.
If you use chrony, the computer hardware clock can be way off (eg local
time) and the linux system will still display correctly, until of course
windows changes the hardware clock.
