postgresql date time at Cygwin On Windows 2000 - workaround available?

Referencing
http://archives.postgresql.org/pgsql-cygwin/2004-03/msg00001.php, is
there any workaround to reset the Postgresql 'system' time as it reads
it from Cygwin?  We have some time-sensitive data, and the Postgresql
time is four days and four hours (plus) off the system time.  We don't
mind having to manually reset periodically, but can't find a way to do
this.  Suggestions?
 
thanks,
Mike
