Dave,

The lag is basically how old a snapshot can be when an editing context goes and looks for it.  The default is an hour, which is usually too long.  The most important caveat:

If the object is already in your editing context, the parameter does nothing (it will stay there forever)

So, when an EC is getting EOs its not currently managing, if the timestamp on the snapshot (the time it was fetched from the database) is greater than the time lag, it will ask for it to be refetched.

Could someone tell me how to control the time that EOF caches an object?  Is it setDefaultFetchTimestampLag?
Does the time get updated if you touch an object while it is cached or is it set once and then dumped when the time expires, no matter what you do?
 
Thanks,
Dave.
