NAME

       DateTime::Infinite - Infinite past and future DateTime objects

VERSION

       version 0.75

SYNOPSIS

	 my $future = DateTime::Infinite::Future->new();
	 my $past   = DateTime::Infinite::Past->new();

DESCRIPTION

       This module provides two DateTime.pm subclasses, "DateTime::Infinite::Future" and "DateTime::Infinite::Past".

       The objects are in the "floating" timezone, and this cannot be changed.

BUGS

       There seem to be lots of problems when dealing with infinite numbers on Win32. This may be a problem with this code, Perl, or Win32's IEEE
       math implementation. Either way, the module may not be well-behaved on Win32 operating systems.

METHODS

       The only constructor for these two classes is the "new()" method, as shown in the SYNOPSIS. This method takes no parameters.

       All "get" methods in this module simply return infinity, positive or negative. If the method is expected to return a string, it return the
       string representation of positive or negative infinity used by your system. For example, on my system calling "year()" returns a number
       which when printed appears either "inf" or "-inf".

       The object is not mutable, so the "set()", "set_time_zone()", and "truncate()" methods are all do-nothing methods that simply return the
       object they are called with.

       Obviously, the "is_finite()" method returns false and the "is_infinite()" method returns true.

NAME

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

SYNOPSIS

	 use DateTime::Format::MySQL;

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

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

DESCRIPTION

       This module understands the formats used by MySQL for its DATE, DATETIME, 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 MySQL 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 MySQL does not provide time zone information.

       * parse_datetime($string)
       * parse_date($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 MySQL stores the local datetime, not UTC.

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

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