Subject: [PATCH] Update documentation references to the time zone database

As of commit 482ff4dae91cf9a288284072d1a299868db7a634, the database
is no longer installed by the GNU C Library.

2014-12-17  Florian Weimer  <fweimer@redhat.com>

	* manual/time.texi (TZ Variable): Update to reflect that the time
	zone database is no longer part of the installation.
	* timezone/README: Likewise.
