NAME

       DateTime::Format::DB2 - Parse and format DB2 dates and times

SYNOPSIS

	 use DateTime::Format::DB2;

	 my $dt = DateTime::Format::DB2->parse_timestamp( '2003-01-16-23.12.01.300000' );

	 # 2003-01-16-23.12.01.300000
	 DateTime::Format::DB2->format_timestamp($dt);

DESCRIPTION

       This module understands the formats used by DB2 for its DATE, TIME, and TIMESTAMP data types.  It can be used to parse these formats in
       order to create DateTime objects, and it can take a DateTime object and produce a string representing it in the DB2 format.

METHODS

       This class offers the following methods.  All of the parsing methods set the returned DateTime object's time zone to the floating time
       zone, because DB2 does not provide time zone information.

       * parse_time($string)
       * parse_date($string)
       * parse_timestamp($string)
	   Given a value of the appropriate type, this method will return a new "DateTime" object.  The time zone for this object will always be
	   the floating time zone, because by DB2 stores the local datetime, not UTC.

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

       * format_date($datetime)
       * format_time($datetime)
       * format_timestamp($datetime)
	   Given a "DateTime" object, this methods returns an appropriately formatted string.

SUPPORT

       Support for this module is provided via the datetime@perl.org email list.  See http://lists.perl.org/ for more details.

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.

       o   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.

       o   parse_date($string)

       o   parse_time($string)

       o   parse_julianday($string)

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

       o   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.

       o   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.

       o   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.

       o   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.
