Browse Source 
Update.
2004-08-09  Ulrich Drepper  <drepper@redhat.com>

	* time/tzset.c (tzset_internal): If TZ is not set do not compare
	old and new tz value since it might be /etc/localtime in both
	cases although the file changed.  [BZ #154]
	Patch by Christian Franke <franke@computer.org>.

	* time/tzfile.c (__tzfile_read): Determine dev/ino of file.
	Compare with values of previously opened file.  Don't do anything
	is they match.
