How do you set the timezone on a BSD system? It defaults to Pacific time. I am running AOS, IBM's port of BSD for the RT, which is very close to the real thing. Please *post* the answer, don't mail it. Thanks. tr@samadams.princeton.edu

In /sys/conf/<YOUR_SYSTEM_NAME>, you will find a line that looks like: timezone 8 dst The "8" is the number of hours that your time zone is West of GMT. Change this to the appropriate thing (e.g., for Eastern time, you would change it to "5"), and rebuild the kernel (i.e., do: % cd /sys/conf % /etc/config <YOUR_SYSTEM_NAME> % cd ../<YOUR_SYSTEM_NAME> % make depend % make which produces a vmunix file - move this to /vmunix [but do remember to save a copy of the old /vmunix first! Copy it to something like /vmunix.old], and reboot). >Please *post* the answer, don't mail it. Why? This is pretty basic stuff - and it's even documented.

Unless the AOS release has the "Arthur Olson" time zone code, you do it by telling the kernel about it. You can do that at configuration time, or by writing a program to use "settimeofday()" to do it.

I'm >only 4.2 though. I believe that Jeff is running UTek, which is a variant of BSD, not plain BSD. Back in the early days of UTek, long before elsie!ado developed the zoneinfo package, we needed a way to allow customers to set the timezone on their local systems. It was not acceptable to have people reconfigure their systems, as binary reconfigurable kernels were not yet common (even if we had them, we had 40MB disk systems to support, so sources, compilers, and even some commands, were optional). So, we opted for modifying the date command to have it set the timezone. As I recall, /etc/rc.local (or whatever we used for this kind of stuff) looked for a file with the timezone name in it, and ran date to set the timezone to this value. For compatability, it wasn't a great move, but in those days it was more important to be able to have more features (HP-UX was the big competitor for us) than to be compatible with other systems (of which there were very few). -- David Elliott dce@smsc.sony.com | ...!{uunet,mips}!sonyusa!dce (408)944-4073 "...it becomes natural, like a third sense." -- Homer Simpson

Look under /etc (whatever the equivalent is). There should be also a directory called "zoneinfo" or "TZ" or something like that. Now, look in that directory for something that looks like a system variable. On the system I use it's called "localtime." To set the time on this system, we link (hard link) EST5EDT to that file (ln EST5EDT localtime). Then used "date" to set the time correctly. A restart of the kernel will then make sure all your time-stamps are correct. But then, that's my system, your mileage probably will vary! ----------------- Roger Jagoda FQOJ@CORNELLA.CIT.CORNELL.EDU My management doesn't even like paying me, let alone acknowledging I work for them! -----------------

That's the Arthur Olson timezone scheme; if your system has it, great, but not all systems do. If there *isn't* a "zoneinfo" in "/etc" or "/usr/share/lib" or any other "obvious" directory, your system probably doesn't have it.
