* doc/tests/clock.test: Added numerous tests for clock scan.

        * doc/generic/tclGetDate.y: Fixed some shift/reduce conflicts in
        clock grammar.

        * doc/doc/clock.n: Added documentation for new supported clock
        scan formats and additional explanation of daylight savings time
        correction algorithm.
