	* glib/gdate.c (g_date_set_time): Don't g_assert that localtime()
	returns non-NULL. It does return NULL at least on Win32 if you
	pass it a negative time_t, which although wrong, shouldn't cause
	an application to abort. Instead return 2000-01-01 as a default
	date. Print a warning unless G_DISABLE_CHECKS. (#164622)
