Jifty::Filter::DateTime -- A Jifty::DBI filter to work with Jifty::DateTime objects
Jifty::Filter::DateTime promotes DateTime objects to Jifty::DateTime objects on load. This has the side effect of setting their time zone based on the record's current user's preferred time zone, when available.
This is intended to be combined with
column created => type is 'timestamp', filters are qw( Jifty::Filter::DateTime Jifty::DBI::Filter::DateTime), label is 'Created', is immutable;
If the value is a DateTime, replace it with a Jifty::DateTime representing the same time, setting the time zone in the process.
