This simplifies time conversions in other time zones. It also prevents display-time-world tampering with TZ (Bug#21020). * admin/admin.el (add-release-logs): Use improved add-log-time-format API. * admin/merge-gnulib (GNULIB_MODULES): Add time_rz, timegm. (GNULIB_TOOL_FLAGS): Avoid flexmember, setenv, unsetenv. * configure.ac (tzalloc): Remove test for this, since Emacs no longer uses HAVE_TZALLOC directly. * doc/lispref/os.texi (Time of Day, Time Conversion) (Time Parsing): * etc/NEWS: Document the new behavior. Merge from gnulib, incorporating: 2015-07-25 strftime: fix newly-introduced bug on Solaris 2015-07-23 fprintftime, strftime: use timezone_t args * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/strftime.c, lib/strftime.h, lib/time.in.h, m4/sys_time_h.m4: * m4/time_h.m4: Update from gnulib. * lib/time_rz.c, lib/timegm.c, m4/time_rz.m4, m4/timegm.m4: New files from gnulib. * lisp/time-stamp.el (time-stamp-string): * lisp/time.el (display-time-world-list) (display-time-world-display): Use new API, with time zone arg. * lisp/time.el (display-time-world-display): Fix race when current-time advances while we're running. * lisp/vc/add-log.el (add-log-iso8601-time-zone) (add-log-iso8601-time-string): Accept optional time zone arg. * lisp/vc/add-log.el (add-change-log-entry): * lisp/vc/log-edit.el (log-edit-changelog-ours-p): Use new arg. * nt/gnulib.mk: Propagate lib/gnulib.mk changes here. Add rules for the time module, since they're now needed for tzalloc etc. * src/conf_post.h (getenv_TZ, setenv_TZ): New macros. (emacs_getenv_TZ, emacs_setenv_TZ): New decls. * src/editfns.c: Include errno.h. (set_time_zone_rule): Omit unnecessary forward decl. (initial_tz): Remove, replacing with ... (local_tz, wall_clock_tz, utc_tz): New static vars and constants. (tzeqlen): New constant; prefer it to (sizeof "TZ=" - 1). (emacs_localtime_rz, emacs_mktime_z, xtzalloc, xtzfree) (tzlookup): New static functions. (init_editfns): New arg DUMPING. All uses changed. (init_editfns): Omit most initialization if dumping, not if !initialized. Initialize wall_clock_tz and local_tz. (emacs_nmemftime, format_time_string): Time zone argument can now be any time zone, not just a boolean for UTC or local time. All callers changed. (Fformat_time_string, Fencode_time, Fcurrent_time_string) (Fcurrent_time_zone): New optional arg ZONE. (Fdecode_time, Fset_time_zone_rule): ZONE arg can now also take the same form as with the other new additions. (decode_time_zone): Remove; no longer needed. (tzvalbuf): Now file-scope. (emacs_getenv_TZ, emacs_setenv_TZ): New functions. (syms_of_editfns): Define Qwall. * src/editfns.c (mktime_z) [!HAVE_TZALLOC]: * src/systime.h (mktime_z, timezone_t, tzalloc, tzfree) [!HAVE_TZALLOC]: Remove; now supplied by gnulib. * src/emacs.c (main): * src/lisp.h (init_editfns): Adjust to init_editfns API change. |
