Time issue

[Ben Novack]

My timezone is set to New York, since I live in the EST timezone.
However, the clock is four hours behind where it should be; if I
manually adjust it, the systemtime is change, so when I reboot into
Windows, I'm four hours <i>ahead</i> of where I should be. Windows'
time is normally set via internet synchronization, so it's going to be
correct. What should I be doing differently in ubuntu to get the time
correct?
