[Zope] [Bug] "bobobase_modification_time" unreliable to catalog

I just discovered that the value cataloged for "bobobase_modification_time" is often wrong: The cataloged value is not the time of the current modification but that of the previous modification. I expect that this is because "bobobase_modification_time" is updated when the transaction is commited while the values to be cataloged are determined before the commit. Do not trust the cataloged "bobobase_modification_time"! Dieter
