SET TIME
Resets the system clock, which is used as a timer to record intervals
between various internal events and as a source clock for displaying
the time of day.
Requires both OPER (operator) and LOG_IO (logical I/O)
privileges.
Format
SET TIME [=time]
Parameter
time
Specifies a date in the format
day-month-year, or a time in the format
hour:minute:second.hundredth, or
both. These fields accept the following values:

The hyphens (-), colons (:), and period (.) are required delimiters.
Separate the date and time, when both are specified, with a colon. The
syntax is sometimes specified as follows:
[dd-mmm-yyyy[:]] [hh:mm:ss.cc]
|
Alpha systems also allow a 2-digit year format:
[dd-mmm-yy[:]] [hh:mm:ss.cc]
|
The century applied to the 2-digit year format is determined by the
corresponding year in the supported Alpha date range (1957-2056). A
2-digit year in the range 57-99 is assumed to mean the years 1957-1999;
a 2-digit year in the range 00-56 is assumed to mean the years
2000-2056. (To specify years outside the 1957-2056 range, you must
enter a 4-digit year.)
If the explicit time value is not specified, the interval system clock
is automatically reset according to the time-of-year clock.
Note that the time-of-year clock is optional for some VAX processors.
For further information about the time-of-year clock, see the hardware
documentation for your computer.
Note
Alpha systems maintain system time during power failures and system
down time. When a system is booted, if the time is known to be earlier
than the time value of the last time modification, or greater than five
years in the future, you are prompted to enter the time at the console
prompt.

Description
Resets the system clock, which is used as a timer to record intervals
between various internal events and as a source clock for displaying
the time of day.
Note
The SET TIME command will not work if there is a time service available
on your system or OpenVMS Cluster.
|
Qualifier
/CLUSTER
Requires OPER and LOG_IO privilege, and in an OpenVMS Cluster
environment, SYSLCK privilege.
Sets the time on all nodes in a cluster to the same system time. The
format of the SET TIME /CLUSTER command is the following:
Format
SET TIME[=time] [/CLUSTER]
Examples
| #1 |
$ SET TIME=14-DEC-2001:19:31:0.0
|
The SET TIME command in this example sets the date and time to December
14, 2001, 7:31 P.M.
| #2 |
$ SET TIME
$ SHOW TIME
14-DEC-2001 03:21:27.53
|
The SET TIME command in this example sets the system time according to
the time-of-year clock. The SHOW TIME command requests a display of the
current time.
| #3 |
$ SET TIME=14-DEC-2001:15:31:0.0/CLUSTER
|
This example sets the date and time to December 14, 2001, 3:31 P.M. on
all nodes in the cluster where the command was entered.
