Hi.

You return false only on failure -- ie: you can't determine the timestamp at
all. The implied condition is then that you can't locate the requested resource
item. Otherwise, you should return true and populate $tpl_timestamp with the
proper timestamp. If you want non-expiring templates and don't intend to
look-up the proper timestamp, set the timestamp for $tpl_timestamp to now
(perhaps with time()).
