* Avoid excessive locking and calling tzset in time functions.Corinna Vinschen2015-04-231-2/+2
| | | | | | | | | | * libc/time/lcltime_r.c (localtime_r): Call _tzset_unlocked inside TZ lock. * libc/time/mktime.c (mktime): Ditto. * libc/time/strftime.c (strftime, wcsftime): Ditto. Guard against calling _tzset_unlocked more than once (baring recursion). Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Move tzset calls to time functions.Craig Howland2015-04-231-0/+2
| | | | | | | | | | * libc/stdlib/setenv_r.c (_setenv_r): Remove tzset() call for TZ definition. * libc/time/lcltime_r.c (localtime_r): Add tzset() call * libc/time/mktime.c (mktime): Ditto. * libc/time/strftime.c (strftime, wcsftime): Ditto. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | * libc/time/mktime.c (mktime): Fix tm_isdst value usage (allowing any positive value from user (per std) rather than depending upon 1).
