Abstract
========

This GLEP proposes using an ISO-8601 compliant date format in GLEPs.

Motivation
==========

The current date format used in GLEPs is ``dd-mmm-yyyy``
(e.g. 14-Aug-2001). This format is not internationalized and not
easily machine parseable.

This GLEP proposes switching to using an ISO-8601 compliant date
format ``yyyy-mm-dd`` (e.g. 2001-08-14). This format is international
and easily machine parseable.

Specification
=============

An overview of the ISO-8601 specification is available online
[#iso-8601]_. Note that only the ``yyyy-mm-dd`` subset of the ISO-8601
specification should be used in GLEPs.

The date(1) utility supports ISO-8601, making it easy for GLEP authors
to get the format right.

Backwards Compatibility
=======================

GLEP 1 should be updated to reflect this new date format, and all
dates in existing GLEPs should be changed to be ISO-8601 compliant.
