Your in Eastern under Daylight savings then :-)

Yep - Windows expects the hardware clock to be in local time, and Unix
usually wants UTC.

I believe the fix is to set in /etc/default/rcS the line UTC=yes to
UTC=no and reboot into Windows.  Make sure the clock is right there,
then boot back into Ubuntu.
