[PATCH] Force rereading TZDEFRULES after it was used to set DST rules only (bug #19253)
- From: Andreas Schwab <schwab at suse dot de>
- To: libc-alpha at sourceware dot org

- Subject: [PATCH] Force rereading TZDEFRULES after it was used to set DST rules only (bug #19253)
- Authentication-results: sourceware.org; auth=none
If the TZDEFRULES file was used to set the DST rules when $TZ didn't
provide any we need to make sure that the next time it is used we
recompute everything as __tzfile_default changes some setting from what is
provided by TZDEFRULES.
Andreas.
[BZ #19253]
* time/tzfile.c (__tzfile_default): Invalidate tzfile attribute
cache when TZDEFRULES was used.
