Can you get details on what value it reports and what it was supposed to 
report? We have to convert from the Windows time scale to a Unix one, 
and it's possible we do it incorrectly.

Also, what time zone is it failing in? We use the current system's 
timezone in the conversion, which may be causing issues.
