hi!
I just solve this
there is function age()
I do that this way
age(datetime(my_timestamp_fld),datetime(now())) > 3600::timespan
But I'm still wonder if all function are write for datetime type.
I thought that timestamp is hmmm... some kind of basic internal
representation of time, so search for such function for type timestamp - I
have 6.3.2 ver. May be in newer version there are already functions for
timestamp type?
