OS X treats days that you go onto daylight saving time as having 23 
hours - and days that you come off DST as having 25 hours. The former 
have 23 hours of seconds, the latter have 25 hours of seconds.

    Please describe the versions of Rev you are using, the operating 
systems on
each platform, and the data and time settings.

It could be daylight savings is one difference between the computers.
At the moment I only have access to OSX, but I am sure someone will be 
able
to help you today.
