Time zone rule is not recreated after a reboot.

[MarkW_1]

OpenVMS 7.3

$ @UTC$TIME_SETUP.COM; show

AUTO_DLIGHT_SAV is set to "1".
OpenVMS will automatically change to/from Daylight Saving Time.
(in timezones that use Daylight Saving Time)

LOCAL TIME ZONE = MOUNTAIN / US -- DAYLIGHT TIME
LOCAL SYSTEM TIME = 7-APR-2005 09:17:18.83
(MDT)
TIME DIFFERENTIAL FACTOR = -6:00
TIME ZONE RULE = MST7MDT6,M4.1.0/02,M10.5.0/02

Rule is not recreated after reboot. Any suggestions

use @net$configure

[MarkW_1]

I noticed that I have been creating empty
SYS$TIMEZONE.DAT; files

[Ian Miller.]

are you running DECnet/Plus and if so is DTSS enabled?

[MarkW_1]

Decnet is not running nor is dtss enabled

Mark,

the *TIME* logicals are being created during system startup by either:

SYS$STARTUP:TDF$UTC_STARTUP.COM or
SYS$STARTUP:DTSS$UTC_STARTUP.COM

using appropriate DTSS$SET_TIMEZONE INITIALIZE ... command (last line in each file).

This is depending on various conditions (DECnet version: Phase IV or Plus, DTSS enabled or correctly disabled by NET$DISABLE_DTSS) and the various TDF related patches.

There have been various problems in the past - see all the patches for VMS731_TDF.
Most of these patches are not available for V7.3.

According to your description, it may be that the startup procedures try to call the wrong *$UTC_STARTUP.COM on your system and therefore fail to define those logicals.

Please check, which *$TDF_STARTUP.COM procedures exist in SYS$STARTUP and check the correct timezone information in those files (last line). Then check which startup procedure is supposed to call that file:

$ SEA SYS$STARTUP:*.COM xxx$UTC_STARTUP
(where xxx is either DTSS or UTC, depending on your system).

Volker.

Mark,

Based on my own dealings with a similar problem, you'll want to be sure that in SYS$MANAGER:SYLOGICALS.COM you define NET$DISABLE_DTSS to 1. This will assist the startup procedure in correctly identifying your configuration and should help it with correctly setting up the time zone rule.

Also, if you have not applied the most recent VMS7*_UPDATE patch kit, nor the *_TDF patch kit then you will want to do that as well, since it did address the logic for correctly setting up the timezone rule at boot time.
