NAME

6       Time::Piece::MySQL - Adds MySQL-specific methods to Time::Piece
7

SYNOPSIS

9         use Time::Piece::MySQL;
10
11         my $time = localtime;
12
13         print $time->mysql_datetime;
14         print $time->mysql_date;
15         print $time->mysql_time;
16
17         my $time = Time::Piece->from_mysql_datetime( $mysql_datetime );
18         my $time = Time::Piece->from_mysql_date( $mysql_date );
19         my $time = Time::Piece->from_mysql_timestamp( $mysql_timestamp );

DESCRIPTION

22       Using this module instead of, or in addition to, "Time::Piece" adds a
23       few MySQL-specific date-time methods to "Time::Piece" objects.
24

OBJECT METHODS

26   mysql_date / mysql_time / mysql_datetime / mysql_timestamp
27       Returns the date and/or time in a format suitable for use by MySQL.
28

CONSTRUCTORS

30   from_mysql_date / from_mysql_datetime / from_mysql_timestamp
31       Given a date, datetime, or timestamp value as returned from MySQL,
32       these constructors return a new Time::Piece object.  If the value is
33       NULL, they will retrun undef.
34
35   CAVEAT
36       "Time::Piece" itself only works with times in the Unix epoch, this
37       module has the same limitation.  However, MySQL itself handles date and
38       datetime columns from '1000-01-01' to '9999-12-31'.  Feeding in times
39       outside of the Unix epoch to any of the constructors has unpredictable
40       results.
41
42       Also, MySQL doesn't validate dates (because your application should);
43       it only checks that dates are in the right format.  So, your database
44       might include dates like 2004-00-00 or 2001-02-31.  Passing invalid
45       dates to any of the constructors is a bad idea: on my system the former
46       type (with zeros) returns undef (previous version used to die) while
47       the latter returns a date in the following month.
