jifty::filter::datetime
Jifty::Filter::DateTime(3pm) User Contributed Perl Documentation Jifty::Filter::DateTime(3pm)NAME
Jifty::Filter::DateTime -- A Jifty::DBI filter to work with
Jifty::DateTime objects
SYNOPSIS
# use it with Jifty::DBI::Filter::Date or J::D::F::DateTime
column created =>
type is 'timestamp',
filters are qw( Jifty::Filter::DateTime Jifty::DBI::Filter::DateTime),
label is 'Created',
is immutable;
DESCRIPTION
Jifty::Filter::DateTime promotes DateTime objects to Jifty::DateTime (or your application's DateTime subclass) 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 "Jifty::DBI::Filter::Date" or "Jifty::DBI::Filter::DateTime", e.g.
column created =>
type is 'timestamp',
filters are qw( Jifty::Filter::DateTime Jifty::DBI::Filter::DateTime),
label is 'Created',
is immutable;
decode
If the value is a DateTime, replace it with a Jifty::DateTime (or your application's subclass) representing the same time, setting the time
zone in the process.
