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/offtime.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'time/offtime.c') diff --git a/time/offtime.c b/time/offtime.c index e588c4c66b..4b8ddb170b 100644 --- a/time/offtime.c +++ b/time/offtime.c @@ -21,7 +21,7 @@ Cambridge, MA 02139, USA. */ /* Defined in mktime.c. */ -extern CONST unsigned short int __mon_lengths[2][12]; +extern CONST unsigned short int __mon_yday[2][13]; #define SECS_PER_HOUR (60 * 60) #define SECS_PER_DAY (SECS_PER_HOUR * 24) @@ -71,10 +71,10 @@ DEFUN(__offtime, (t, offset, tp), } tp->tm_year = y - 1900; tp->tm_yday = days; - ip = __mon_lengths[__isleap(y)]; - for (y = 0; days >= ip[y]; ++y) - days -= ip[y]; + ip = __mon_yday[__isleap(y)]; + for (y = 11; days < ip[y]; --y) + continue; + days -= ip[y]; tp->tm_mon = y; tp->tm_mday = days + 1; - tp->tm_isdst = -1; } -- cgit v1.2.3
