Port mktime_internal offset to unsigned time_t This avoids some assumptions about wraparound arithmetic on signed integer overflow. * lib/mktime-internal.h (mktime_offset_t): New type. (mktime_internal): Use it in decl. * lib/mktime.c, lib/timegm.c (mktime_offset_t) [_LIBC]: New type. * lib/mktime.c (__mktime_internal, localtime_offset): * lib/timegm.c (timegm): Use it. * m4/mktime.m4 (gl_TIME_T_IS_SIGNED): New macro. (gl_FUNC_MKTIME): Require it.
