[Zope] bobobase_modification_time off by 1 day - why?

[Luke Tymowski]

Hello,

Zope reports the bobobase_modification_time  to be off by one day (1 day 
behind). The box has the right time (when checked from the OS), and asking 
Zope to return ZopeTime returns the correct date and time.

Anyone know why?

thanks,

Luke
