These are hex encoded timestamps. It indicates that part of a transaction from 
Tue Feb  4 20:46:17 2003 is mixed up with the transaction record from 
Sun Feb  9 12:51:24 2003

Do these times seem significant?

This is indicating a bad FileStorage, not a bad object. Deleting an object 
might not make the problem go away, and might make it worse.

A few people have been reporting this recently, and sadly noone has a good 
answer for this FileStorage problem. If you can reproduce the problem 
starting with a clean FileStorage then I am sure a FileStorage developer will 
take a look.
