Remove explicit error handling for obsolete date/time values
author Peter Eisentraut <peter@eisentraut.org>

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.
