NAME

       DateTime::Format::SQLite - Parse and format SQLite dates and times

SYNOPSIS

         use DateTime::Format::SQLite;

         my $dt = DateTime::Format::SQLite->parse_datetime( '2003-01-16 23:12:01' );

         # 2003-01-16 23:12:01
         DateTime::Format::SQLite->format_datetime($dt);

DESCRIPTION

       This module understands the formats used by SQLite for its "date", "datetime" and "time"
       functions.  It can be used to parse these formats in order to create DateTime objects, and
       it can take a DateTime object and produce a timestring accepted by SQLite.

       NOTE: SQLite does not have real date/time types but stores everything as strings. This
       module deals with the date/time strings as understood/returned by SQLite's "date", "time",
       "datetime", "julianday" and "strftime" SQL functions.  You will usually want to store your
       dates in one of these formats.

METHODS

       This class offers the methods listed below.  All of the parsing methods set the returned
       DateTime object's time zone to the UTC zone because SQLite does always uses UTC for date
       calculations.  This means your dates may seem to be one day off if you convert them to
       local time.

       •   parse_datetime($string)

           Given a $string representing a date, this method will return a new "DateTime" object.

           The $string may be in any of the formats understood by SQLite's "date", "time",
           "datetime", "julianday" and "strftime" SQL functions or it may be in the format
           returned by these functions (except "strftime", of course).

           The time zone for this object will always be in UTC because SQLite assumes UTC for all
           date calculations.

           If $string contains no date, the parser assumes 2000-01-01 (just like SQLite).

           If given an improperly formatted string, this method may die.

       •   parse_date($string)

       •   parse_time($string)

       •   parse_julianday($string)

           These are aliases for "parse_datetime", for symmetry with "format_*" functions.

       •   format_date($datetime)

           Given a "DateTime" object, this methods returnes a string in the format YYYY-MM-DD,
           i.e. in the same format SQLite's "date" function uses.

       •   format_time($datetime)

           Given a "DateTime" object, this methods returnes a string in the format HH:MM:SS, i.e.
           in the same format SQLite's "time" function uses.

       •   format_datetime($datetime)

           Given a "DateTime" object, this methods returnes a string in the format YYYY-MM-DD
           HH:MM:SS, i.e. in the same format SQLite's "datetime" function uses.

       •   format_julianday($datetime)

           Given a "DateTime" object, this methods returnes a string in the format DDDDDDDDDD,
           i.e. in the same format SQLite's "julianday" function uses.
