YMD to ISO/doc

Template:YMD to ISO converts a date in YMD format (e.g. 2000 January 17) to ISO 8601 format (e.g. 2000-01-17). Any input which is not a valid DMY date is passed through unchanged. This template is designed to preprocess dates for use with the #time parser function, which is unable to convert YMD dates, and for use with templates such as {{Date}} or {{ISO date}} which are implemented using the #time parser function.

Usage

{{YMD to ISO | <date in YMD format> }}
