tzset not defined on all platforms

[vervaekejonathan]

tzset was not defined on my platform

#if __POSIX_VISIBLE
_VOID _EXFUN(tzset, (_VOID));
#endif
_VOID _EXFUN(_tzset_r, (struct _reent *));

Fixed by using _tzset_r instead of tzset

Thanks for the info. What is your platform? Operating system and compiler, please. Including versions.

Same issue.
I defined HAS_TZ in addition to HAS_GMTIME_R, HAS_LOCALTIME_R and HAS_TIMEGM.
Microchip compiler XC32 v1.40, for PIC devices.
TZ is available with the "Legacy libc" but not with the default microchip lib.
