From: Lou Salkind <salkind@nyu> Subject: Time zone is not set in settimeofday Index: sys/sys/kern_time.c 4.2BSD Description: The timezone field in the settimeofday system call is ignored. (I discovered this when I tried to change the PST timezone on our Pyramid system.) Repeat-By: Run the program below and you will see no difference. Fix: In kern_time.c:settimeofday(), just after the second if (u.u_error) return; add tz = atz; Also, the following program will allow you to change the timezone: ----- timezone.c ----- /* * timezone minuteswest [dsttime] */ #include <stdio.h> #include <sys/time.h> struct timeval tv; struct timezone tz; main(argc, argv) int argc; char *argv[]; { if (argc < 2) exit(0); gettimeofday(&tv, &tz); tz.tz_minuteswest = atoi(argv[1]); if (argc > 2) tz.tz_dsttime = atoi(argv[2]); if (settimeofday(&tv, &tz) < 0) { perror("settimeofday"); exit(1); } exit(0); }
