[CQ-Contest] Cabrillo or Writelog fix for off by one hour in log file?

[Dan Levin]

In a fit of idiocy, I operated SS with my computer's clock
off by one hour.  Now my log has all the times wrong.

I know I'm not the first person to do this, but I couldn't
find the thread in the archive...

Does anyone have an easy way to fix this, either in Writelog
or in my Cabrillo file? I basically need to change each
QSO's time stamp by one hour.

Thanks!
