Time::Piece::ISO version 0.13

This module subclasses Matt Seargent's Time::Piece module in order to change its stringification and string comparison behavior to use the ISO 8601 format instead of localtime's ctime format. Although it does break the backwards compatibility with the builtin localtime and gmtime functions that Time::Piece offers, Time::Piece::ISO is designed to promote the more standard ISO format as a new way of handling dates.

I decided to create this module for two simple reasons: First, default support for the ISO 8601 date format seems to be the direction in which Perl 6 is heading. And second, the ISO 8601 format tends to be more widely compatible with RDBMS date time column type formats.

That said, the DateTime module has since come to be, and it should probably be preferred to this module whenever possible.


To install this module, type the following:

perl Build.PL
./Build test
./Build install

Or, if you don't have Module::Build installed, type the following:

perl Makefile.PL
make test
make install


This module subclasses and requires the Time::Piece module from the CPAN.
