| | | | | | * src/timefns.c (decode_lisp_time) [FASTER_TIMEFNS]: Speed up when SPECIFIED_TIME is an integer. (time_cmp) [FASTER_TIMEFNS]: Speed up when comparing integers.
* Decode time conses before floatsPaul Eggert2022-08-141-11/+11
| | | | | * src/timefns.c (decode_lisp_time): Test for conses before floats, as conses are more common.
* * lisp/calendar/time-date.el (seconds-to-time): Use the original arg listStefan Monnier2022-08-141-3/+10
|
* Document time-convert FORM argument as mandatoryBasil L. Contovounesios2022-08-131-3/+2
| | | | | | | | | This is a followup to commit b70369c557 of 2022-08-05 "time-convert): Deprecate calls without an explicit FORM arg". * doc/lispref/os.texi (Time Conversion): * src/timefns.c (Ftime_convert): Describe FORM argument as required as per the advertised calling convention.
* Improve time-convert docstring formatting for readabilityStefan Kangas2022-08-131-6/+12
| | | | | * src/timefns.c (Ftime_convert): Doc fix; improve formatting for readability.
* * src/timefns.c (Ffloat_time): Fix doc string.Paul Eggert2022-08-011-1/+1

* Improve time-equal-p etc. performancePaul Eggert2022-08-011-1/+7
| | | | | | * src/timefns.c (time_cmp): Return EMACS_INT, not int; no need to change callers. Compare (X . Z) to (Y . Z) quickly if X and Y are fixnums.
* Improve float-time etc. performancePaul Eggert2022-08-011-20/+19
| | | | | | | | | | | * src/timefns.c (decode_float_time): Assume T is finite. All callers changed. (decode_time_components): Assume FORM is not TIMEFORM_FLOAT. All callers changed. (decode_lisp_time): If the specified time is a float, signal an error if it is not finite. (Ffloat_time): If the specified time is a float, simply return it.
* Make time arithmetic more like comparisonPaul Eggert2022-08-011-33/+11
| | | | | | | | | | | Since time comparison says X == X, have time arithmetic behave similarly for X - X. This should also be a bit faster due to not having to test for floats and NaNs. * src/timefns.c (time_arith, time_cmp): Simplify by not worrying about NaNs, which are not time values. (time_arith): Simplify by not worrying about subtracting nil from nil; the caller now handles this. (Ftime_subtract): Handle subtracting X from X specially.
* (time-equal-p nil X) returns nilPaul Eggert2022-08-011-1/+3
| | | | * src/timefns.c (Ftime_equal_p): nil compares unequal to non-nil.
* Improve time parsing documentationLars Ingebrigtsen2022-06-171-1/+1
| | | | | | * doc/lispref/os.texi (Time Parsing): Clarify which functions take/return timestamps and which ones take decoded time structures. * src/timefns.c (Fdecode_time): Clarify TIME argument (bug#46505).
* Streamline time decoding and conversionPaul Eggert2022-06-151-7/+9
| | | | | | * src/lisp.h (lisp_h_BASE2_EQ, BASE2_EQ): New macros and functions. * src/timefns.c (tzlookup, Fdecode_time): Use them. (Ftime_convert): Convert to symbol once, instead of many times.
* Prefer BASE_EQ in time-sensitive opsPaul Eggert2022-06-151-15/+15
| | | | | | | * src/timefns.c (tzlookup, lisp_time_hz_ticks) (decode_time_components, lisp_to_timespec, lispint_arith) (time_arith, time_cmp, Fdecode_time, Fencode_time) (Ftime_convert): Prefer BASE_EQ to EQ where either will do.
* ; Fix typo in documentation of 'current-time-list'Eli Zaretskii2022-04-291-1/+1
| | | | | | * src/timefns.c (syms_of_timefns) <current-time-list>: * etc/NEWS: * doc/lispref/os.texi (Time of Day): Fix a typo.
* Change current-time back to list formPaul Eggert2022-04-281-17/+31
| | | | | | | | | | | Change current-time and related functions back to using the traditional list form. Also, add a new boolean variable current-time-list that lets people try out (TICKS . HZ) form, with the goal of smoothing the transition. * src/timefns.c (CURRENT_TIME_LIST): Change default back to true. (current-time-list): New boolean Lisp variable, which defaults to CURRENT_TIME_LIST. All uses of CURRENT_TIME_LIST changed to use current_time_list, and all documentation changed.
* Add new function current-cpu-timeStefan Monnier2022-04-271-0/+15
| | | | | * doc/lispref/os.texi (Time of Day): Document it. * src/timefns.c (Fcurrent_cpu_time): New function (bug#44674).
* Use (TICKS . HZ) for current-time etc.Paul Eggert2022-04-251-14/+12
| | | | | * src/timefns.c (CURRENT_TIME_LIST): Change default to false. All documentation changed.
* Support (encode-time (list s m h D M Y))Paul Eggert2022-04-251-6/+15
| | | | | | * src/timefns.c (Fencode_time): Add support for a 6-elt list arg. Requested by Max Nikulin for Org (bug#54764). * test/src/timefns-tests.el (encode-time-alternate-apis): New test.
* Document encode-time caveatsPaul Eggert2022-04-161-9/+7
| | | | | | | | | | | | | | | | * doc/lispref/os.texi (Time of Day, Time Conversion): Move the warnings about DST being -1 to closer to where DST is discussed, and reword and improve the discussions and warnings. Be more precise about years before 1969 (possible west of UTC) vs the Epoch. Mention some problems due to leap seconds, leap years, daylight saving transitions, and time zone changes. Modernize discussion of OS timestamp range. Prefer secular ‘BCE’ to religious ‘BC’. Omit discussion of decoded-time-add and make-decoded-time, as they are in a library and are not always available; instead, mention the library. Warn about common mistakes when doing simple date arithmetic. * src/timefns.c (Fencode_time): In doc string, mention date arithmetic and tighten up the wording a bit.
* Stress difference of new and old ways to call `encode-time'Max Nikulin2022-04-161-0/+4
| | | | | | | | | | | | | | | * doc/lispref/os.texi (Time Conversion): Add a warning that blind changing of code calling `encode-time' to use single list instead of multiple values may cause deferred bugs since it is common to use nil for ignored arguments such as DST in the old calling convention. * src/timefns.c (encode-time): Mention the warning added to the elisp reference in the docstring. Refactoring related to `encode-time' caused (bug#54731), so it is better to make apparent the difference between the recommended and the obsolescent ways to call the function. More details concerning the purpose and limitations of the DST field are added after discussion with Paul Eggert in (bug#54764).
* New time-equal-p testPaul Eggert2022-04-141-1/+2
| | | | * test/src/timefns-tests.el (time-equal-p-NaN-NaN): New test.
* Avoid possibly unnecessary lisp_time_struct callPhilip Kaludercic2022-04-141-2/+1
| | | | | * timefns.c (time_cmp): Defer the calculation of the time struct, in case A and B are eq to one another.
* Remove unused fns/data and make fns staticPaul Eggert2022-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | * src/comp.c (saved_sigset, helper_temp_output_buffer_setup): Remove; unused. * src/comp.c (logfile, helper_link_table): * src/fns.c (hashfn_equal, hashfn_eql): * src/frame.c (frame_windows_min_size): * src/gnutls.c (emacs_gnutls_global_init): * src/minibuf.c (Vcommand_loop_level_list): * src/syntax.c (syntax_code_spec): * src/timefns.c (time_overflow): * src/xterm.c (x_xrender_color_from_gc_foreground) (x_display_set_last_user_time): Now static, since it’s not used elsewhere. * src/xterm.c (x_xrender_color_from_gc_foreground) (x_xrender_color_from_gc_background): Move earlier to avoid forward use. (x_xrender_color_from_gc_foreground): Do not define unless !defined USE_CAIRO && (RENDER_MAJOR > 0 || RENDER_MINOR >= 2), since it’s not used otherwise.
* Fix process-attributes time precision on GNU/LinuxPaul Eggert2022-03-041-1/+1
| | | | | | | | | | | | | | | * src/sysdep.c [GNU_LINUX]: (time_from_jiffies): Simplify by using time-convert. Change args and result type. All uses changed. (ltime_from_jiffies): Remove; call time_from_jiffies instead. (put_jiffies): New function. (get_up_time): Return Lisp_Object not struct timespec. All uses changed. Simplify by using time-add. (system_process_attributes): Simplify by using the above. This fixes some minor problems where timestamps promised more precision than was actually available. When info is not available (e.g., sysconf fails) do not place it into the alist. * src/timefns.c (float_time): Now extern.
* Avoid unnecessary make_float in time arithmeticPaul Eggert2022-03-041-4/+12
| | | | | * src/timefns.c (float_time): New function. (time_arith, Ffloat_time): Use it.

* | Omit temporary warning re obsolete timestampsPaul Eggert2021-12-161-49/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Do not warn about timestamps like (1 . 1000). This warning was added in Emacs 27 as a temporary transition aid, and has now served its purpose. These timestamps, which Emacs 26 and earlier treated as (HI . LO) instead of as (TICKS . HZ), were never generated by Emacs primitives, and in practice the warning seems to have been triggered only by test cases designed to generate it. * src/timefns.c (WARN_OBSOLETE_TIMESTAMPS): Remove. All uses changed to assume it’s false. (decode_lisp_time): Simplify by taking a bool instead of an integer bitmask. All uses changed.
* | Fix encode-time doc stringPaul Eggert2021-12-161-6/+5
|/ | | | | | * src/timefns.c (Fencode_time): Fix incorrect doc string that talks about FORM (which doesn’t exist) by copying wording from the manual instead.
* Work around GCC bug 102671Paul Eggert2021-10-111-0/+5

* Simplify format_time_stringPaul Eggert2020-08-161-18/+15
| | | | | | * src/timefns.c (emacs_nmemftime, format_time_string): Simplify on the basis of recent nstrftime changes. Propagate nstrftime errno.
* Prefer make_nil_vector to make-vector with nilPaul Eggert2020-08-111-1/+1
| | | | | | | * src/pdumper.c (hash_table_thaw): Pacify -Wconversion so we can use make_nil_vector again. * src/timefns.c (syms_of_timefns): Prefer make_nil_vector to make_vector with Qnil.
* Tiny simplification of frac_to_doublePaul Eggert2020-03-191-2/+1
| | | | | * src/timefns.c (frac_to_double): Remove unnecessary runtime check, since the denominator is always positive.
* Omit timestamp optimization invalid on 387 FPUPaul Eggert2020-03-191-3/+0
| | | | | | * src/timefns.c (frac_to_double): Omit optimization that is invalid on machines with excess precision (e.g., gcc x86 with 387 FPU), because it double-rounds. Found via ‘gcc -m32’ on x86-64.
