[ZODB-Dev] problem with _p_mtime

[Miles]

Hi,

I've moved a FileStorage from one (old) machine to another (new) 
machine, but when I mount it on the new machine I get a lot of time errrors:

Traceback (innermost last):
   Module ZPublisher.Publish, line 115, in publish
   Module ZPublisher.mapply, line 88, in mapply
   Module ZPublisher.Publish, line 41, in call_object

   Module DateTime.DateTime, line 509, in __init__

   Module DateTime.DateTime, line 437, in safelocaltime
TimeError: The time 98040302366.810165 is beyond the range of this 
Python implementation.

I googled around on this problem and didn't find much, but I did find 
that as a temporary fix, I've put a try/except in App.PersistentExtra, 
so if it generates an exception, it returns the current date and time. 
This keeps things working.

Out of interst, can anyone tell me why there is a difference?  On both 
machines, python was compiled from source with the same options, so I'm 
not sure what this is down to.

More importantly, what's the most straightforward way to set all the 
dates to usable values?  From my POV, it's fine to set them all to the 
current date, but I don't know how to go about doing this exhaustively.

Thanks for your help,

Miles
