Timezone Dfferential gone after reboot

Jakes Bruwer — Tue, 18 Sep 2007 07:33:01 GMT

Good day,
I'm running OpenVMS V7.3-2 on Alpha.
I configure a time differential value of 2:00 with the timezone "Zulu", using UTC$Time_Setup.com. After the configuration, the logicals look like this:

"SYS$LOCALTIME" = ZULU."
"SYS$TIMEZONE_DAYLIGHT_SAVING" = "0"
"SYS$TIMEZONE_DIFFERENTIAL" = "7200"
"SYS$TIMEZONE_NAME" = "GMT"
"SYS$TIMEZONE_RULE" = "GMT0"

This is how I want it, but then when I reboot the server and it is back up again the timezone differential is back to "0".

I tried to use net$configure, but this procedure does not ask me if I want a timezone differetial factor.

Any help would be appreciated.

Jakes

Jakes,

Have you tried selecting Africa then Johannesburg (item 28) when running UTC$Time_Setup.com?

Not sure if selecting ZULU is correct for your location. I thought that ZULU time, by definition, would indeed have a differential of 0, which is what you're seeing after reboot.

Zulu time definitely as a differential of zero. you need to select another zone.

For timezone information to remain permanent, the net$configure command procedure, option 5 must be used. Use a timezone with a 2 hour differential, even if it is not your own country.

Jakes,

"For timezone information to remain permanent, the net$configure command procedure, option 5 must be used. Use a timezone with a 2 hour differential, even if it is not your own country."

Just curious, what and where is this net$configure procedure?

Also, from your OP:

"I tried to use net$configure, but this procedure does not ask me if I want a timezone differential factor."

So how could using this net$configure create or adjust a TDF?

Now netconfig in sys$manager is a familiar procedure, but it does not deal with time, it deals with DECnet configuration items.

Hi Dave,
The conclusion I put in the closing thread of my question, was just a shortened version of what I did. To elaborate a bit; The net$configure command procedure is used to configure Decnet, but it also has a option (5) Configure Timezone Differential Factor. It then also asks you to choose a timezone. Because it does not ask me for a timezone differential factor after I choose the timezone, I played around and chose timezones, until I found one that has a -2 hour time differential by default. I chose GABORONE which has a -2 hours time diff. This timezone is now permanent and does not disapear after a reboot and it is what I wanted eventhough I'm not anyware near Gabarone. At least I am in Africa (south).
Hope this shead some more light?

Sounds like it might be some confusion or a full-on in the DECnet-Plus kit somewhere; timekeeping and timezones and DST switch-over (save for the task of network time synchronization) was moved from DECnet-Plus DECdts DTSS into the base operating system at V7.3.

If you have a support contract, you might want to ping HP support and ask that this stuff be looked at.

I'd trust UTC$TIME_SETUP here, and would not think to use NET$CONFIGURE for this task.
