	* configure.in: add gio check for CLOCK_MECHANISM, because of the use
	of system-timezone.c

2008-04-10  Vincent Untz  <vuntz@gnome.org>

	Rewrite the code to set the system timezone. It should work on most
	distributions now, instead of only the ones doing the same thing as
	Fedora. Like the rewrite to get the timezone, it helps improve the
	world.

	* Makefile.am: fix typo and add system-timezone.[ch] to
	gnome_clock_applet_mechanism_SOURCES
	* gnome-clock-applet-mechanism.c:
	(gnome_clock_applet_mechanism_set_timezone): just call
	system_timezone_set_from_file()
	* system-timezone.[ch]: add clear comments and some code to easily test
	the functions
	Also add comments on our current knowledge about system timezones on
	the various distributions.
	(system_timezone_constructor),
	(system_timezone_finalize): fix the same singleton issue as the one
	fixed in the previous commit
	(system_timezone_write_etc_timezone),
	(system_timezone_write_key_file),
	(system_timezone_write_etc_TIMEZONE),
	(system_timezone_write_etc_sysconfig_clock),
	(system_timezone_write_etc_sysconfig_clock_alt),
	(system_timezone_write_etc_conf_d_clock),
	(system_timezone_is_zone_file_valid),
	(system_timezone_set_etc_timezone),
	(system_timezone_update_config), (system_timezone_set_from_file),
	(system_timezone_set), (system_timezone_error_quark): well, all new. To
	do some magic things. Some code is loosely based on what was in
	gnome-clock-applet-mechanism.c
