6.2 Setting Time Zone Information on OpenVMS Alpha Version 7.3
and Later
This section contains instructions for setting time zone information on OpenVMS
Alpha Version 7.3 and later. For instructions on setting time sone information on
OpenVMS Alpha prior to Version 7.3 and on OpenVMS VAX, see Section 6.3.
Note
If you are using the Distributed Time Synchronization Service (DTSS),
you must use the procedures supplied with DTSS to set time zone
information. See Section 6.1.1.
Use the procedure SYS$MANAGER:UTC$TIME_SETUP.COM to set time zone
information.
Note
SYS$MANAGER:UTC$TIME_SETUP.COM has some undocumented
uses that are not supported and can lead to inconsistent or
incorrect time zone information, For this reason, you should use
SYS$MANAGER:UTC$TIME_SETUP.COM only in the ways that are
documented here.
To use SYS$MANAGER:UTC$TIME_SETUP.COM, you must have the following
privileges enabled: OPER, LOG_IO, SYSPRV, SYSNAM and CMEXEC. To ensure
that these privileges are enabled, execute the following command:
$ SET PROCESS/PRIVILEGES=(OPER,LOG_IO,SYSPRV,SYSNAM,CMEXEC)
If these privileges are not enabled, you can encounter errors or incorrect results.
You can use SYS$MANAGER:UTC$TIME_SETUP.COM to display current time
zone information or to set time zone information.
6.2.1 Displaying Time Zone Information
After ensuring that the required privileges are enabled (see Section 6.2), execute
the following command:
$ @SYS$MANAGER:UTC$TIME_SETUP SHOW
