* tests/clock.test: added clock-9.1

	* compat/strftime.c:
	* generic/tclClock.c:
	* generic/tclInt.decls:
	* generic/tclIntDecls.h:
	* unix/tclUnixTime.c: fix for Windows msvcrt mem leak caused by
	using an env(TZ) setting trick for in clock format -gmt 1.  This
	also makes %s seem to work correctly with -gmt 1 as well as
	making it a lot faster by avoid the env(TZ) hack.  TclpStrftime
	now takes useGMT as an arg.  [Bug #559376]
