NAME
       Date::Manip::TZdata -- Internal module for working with the tzdata
       files

SYNOPSIS
	  use Date::Manip::TZdata;

	  $tzd	= new Date::Manip::TZdata($dir);

DESCRIPTION
       This module is not intended for public use. It is used internally by
       the scripts used	to analyze the time zone database and generate the
       modules for each	time zone. The module is included in the distribution
       solely for the sake of completeness. Currently, no support is offered
       for this	module,	and it can (and	may) change without notice.

       This module consists of routines	for working with the tzdata files.
       These files are updated several times a year and	are the	basis for time
       zone descriptions for most computer systems.

ROUTINES
       new
	      use Date::Manip::TZdata;

	      $tzd  = new Date::Manip::TZdata($dir);

	   This	finds and reads	in all the tzdata. If $dir is passed in, it is
	   the directory where a tzdata	directory is located. It defaults to
	   the current directory.

KNOWN LIMITATIONS
       Some assumptions	and limitations	are assumed in the logic of this
       module.

       When a time change occurs, the time may change backwards	or forwards.
       Time changes rules are listed on	a per-year basis.  It is assumed that
       time changes will not occur so close to the end or start	of the year as
       to cross	the year boundary (in other words, the year will not change as
       a result	of the time change).  This is not accounted for, and it	is
       hoped that this situation will never occur.

       Also, because this module is strictly limited to	4 digit	positive years
       (regardless of whether it is wall clock or universal time), and because
       various parts of	the module switch back and forth, valid	times for this
       module are from Jan 2, 0001 to Dec 30, 9999. This ensures that
       conversions from	wall clock to universal	or vice	versa will never make
       dates occur in the year 0000 or 10000.

KNOWN BUGS
       None known.

BUGS AND QUESTIONS
       Please refer to the Date::Manip man page	for information	on submitting
       bug reports or questions	to the author.
