fprintftime, strftime: use timezone_t args * NEWS: Document the change. * lib/fprintftime.h (fprintftime): * lib/strftime.c (extra_args) [my_strftime]: * lib/strftime.h (nstrftime): Time zone arg is now of type timezone_t, not int. * lib/strftime.c (mktime_z) [_LIBC]: New macro. (__gmtime_r, __localtime_r) [!HAVE_TM_GMTOFF]: Remove; no longer used. (my_strftime) [emacs && !my_strftime]: (emacs_strftimeu) [emacs && !FPRINTFTIME]: Remove; Emacs doesn't need this any more. (HAVE_TZSET) [my_strftime]: Unset, since we no longer want fprintftime and nstrftime to call tzset. (ut) [!my_strftime]: Remove, replacing with ... (tz) [!my_stftime]: ... this new macro. All uses changed. (strftime_case_): Use localtime_rz and mktime_z instead of localtime_r and mktime. * modules/fprintftime (Depends-on): Add time_rz. * modules/strftime (Depends-on): Add time_rz. Remove time_r. * tests/test-strftime.c (main): Adjust to new nstrftime API.
