Remove explicit error handling for obsolete date/time values
The date/time values 'current', 'invalid', and 'undefined' were removed a long time ago, but the code still contains explicit error handling for the transition. To simplify the code and avoid having to handle these values everywhere, just remove the recognition of these tokens altogether now. Reviewed-by: Michael Paquier <michael@paquier.xyz>
