I'd like to keep a last update timestamp on my entities. Would
validateForSave | validateForUpdate be a good time to modify an

Define good. :-) That violates an EOF commandment. You risk
confusing EOF. If you are using Wonder, there is a facility in
ERXEC to have it notify your object at a safe time to do this.
Use ERXGenericRecord from Wonder.
It has willUpdate, willInsert etc that are perfect for this sort of
thing.
They are called after saveChanges but before validation so it is
safe to make changes.
Yes, that is what I was thinking of. IIRC works in concert with the EC.
