Welcome to the Cmdr project, written by Andreas Kupries.

For availability please read Cmdr - How To Get The Sources.

This package provides the validation type ::cmdr::validate::date which accepts dates in ISO 8601 syntax.

The internal representation is the epoch for the validated input, at midnight.

The type has no input completion.

The details of the exported standard API can be found in Cmdr - Writing custom validation types. The chosen default is "today".

A single non-standard method is provided:

::cmdr::validate::date 2external epoch

This method converts the epoch of a date to the form %Y-%m-%d and returns the conversion result as its own.
