Fix some minor time-related bugs with POSIX time arguments.

	Some valid time stamps were being rejected (notably -1, and
	time stamps before 1900 on 64-bit hosts).  And some invalid
	time stamps were being accepted, e.g. September 31.

	* posixtm.h (posixtime): Return bool instead of time_t, so
	that we can return (time_t) -1 successfully.
