Use tools::Time::GetClock() in number formatter for wall clock time

Also handle rounding/scaling better in ImpGetTimeOutput() for the
[] duration formats, of which [HH]:MM:SS(.0000000) is used to edit
time values.

The wall clock change made it necessary to adapt some test cases in
Test::testUserDefinedNumberFormats() where M_PI formatted to
date+time actually is 1900-01-02 03:23:53.60527 with second 53
instead of the previously rounded 54.
