From 80fd73873bd51e58039983a9416ef3bb97bdac57 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 6 Oct 1995 04:50:55 +0000 Subject: Fri Sep 29 03:43:51 1995 Paul Eggert Rewrite mktime from scratch for performance, and for correctness in the presence of leap seconds. * time/mktime.c (ydhms_tm_diff, not_equal_tm, print_tm, check_result): New functions. (LEAP_SECONDS_POSSIBLE, CHAR_BIT, INT_MIN, INT_MAX, TIME_T_MIN, TIME_T_MAX, TM_YEAR_BASE, EPOCH_YEAR): New macros. , : New #includes. (main): Support tests with given broken-down value; support benchmarks. (__mon_lengths, debugging_enabled, printtm, dist_tm, doit, do_normalization, normalize, BAD_STRUCT_TM, SKIP_VALUE, ): Remove. * time/time.h, time/mktime.c (__mktime_internal): New offset arg. * time/mktime.c (mktime), time/timegm.c (timegm): Use it. * time/mktime.c (__mon_yday): New variable; replaces `__mon_lengths'. time/offtime.c (__offtime), time/tzset.c (compute_change): Use it. * time/offtime.c (__offtime): Remove useless assignment `tp->tm_isdst = -1'. * manual/maint.texi: Update credits. Fri Oct 6 00:28:53 1995 Roland McGrath * sysdeps/unix/common/readv.S: Moved to sysdeps/unix/bsd. * sysdeps/unix/common/writev.S: Moved to sysdeps/unix/bsd. * sysdeps/unix/sysv/linux/readv.c: File removed. * sysdeps/unix/sysv/linux/writev.c: File removed. * sysdeps/unix/configure.in: Check for readv and writev syscalls. * sysdeps/unix/configure.in: If eval doesn't set $unix_srcname, set it to $unix_syscall instead of $unix_function. --- time/timegm.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'time/timegm.c') diff --git a/time/timegm.c b/time/timegm.c index f63aac9..4dd87f4 100644 --- a/time/timegm.c +++ b/time/timegm.c @@ -22,6 +22,7 @@ time_t timegm (tmp) struct tm *const tmp; { + static time_t gmtime_offset; tmp->tm_isdst = 0; - return __mktime_internal (tmp, __gmtime_r); + return __mktime_internal (tmp, __gmtime_r, &gmtime_offset); } -- cgit v1.1
