Date and time settings

Sprint Unix Team — Thu, 25 Oct 2001 13:11:05 GMT

When we do a set_parms, we set time and day settings and this is taken care when there is day light settings.

Now, when we do recover a box by make_net_recovery, does it take care of the time and date settings..if not is there any command other than set_parms to change date..

what is the daemon for this process???

The make_net_recovery will set the timezone appropriately. As I understand it, the system time/date are set in non-volatile memory, so the hardware keeps track of time in UTC (universal time coordinates). The OS translates from UTC to the local time using the timezone settings. Hope this helps.

Hi:

/etc/TIMEZONE would be a part of the vg00 (obviously) so thus the timezone established by /sbin/set_parms would carry along.

If you look in /etc/profile you will see that /etc/TIMEZONE is interrogated during login.

The easiest way I know for setting the date is like this fro 10/20/01 9:25 am. # date 102009252001. This will change the date for you. Also when you recover from a make_recovery you can interrupt and do an interactive restore. This will allow you to set the date also.

Make_recovery doesn't change
the running clock of the system.

If you are restoring in
the same site/timezone on
a hardware which is on the site, on which you took the tape-recovery, nothing needs to be done .

But, if you are taking the
tape and restoring it on
a different TZ , you would
need to run set_parms to
change it, which is the reliable way to do it.
