I've pushed a patch that make things faster:

https://git.claws-mail.org/?p=claws.git;a=commitdiff;h=f6016ef46503a7bac437a3f2ada7d9d0cde60edc

That's still orders of magnitude slower to use "test", forking a shell
etc, than age_lower/age_greater, because the latter works on a cached
timestamp. 

I'm not against adding a "date_lower/date_greater" filtering criteria, I
could use it myself.
