solaris 8 how to change time immediately
Posted on 2005-04-14
Today we did a restore excercise on our SUN netra 240 platform.
This is a 4 box redundant softswitch, meaning softswitch is contained in two boxes with a redundant pair.
The element managing box, is sync'ed via NTP server and also acting as NTP server to the "slave boxes".
This was a twostep recovery, Flash-archive(flarcreate) and application as a normal GZ/tar thing.
However during Cd-rom boot (Solaris disk1) we bummed setting up the time. We set it up as CET, but we entered the time as CEST, so now we end up with an extra daylight savings hour, in other words we are 1 hour ahead in time.
We just thought wth - NTP will take care of this, and it will, but it takes ~ 16 hours to skew(right word else insert adjust) 1 hour.
If this was not our testsite, but in real life is there any other way to remedy this than:
Stop application and on SOLARIS level do a < date YYMMDDHHMSS
reboot necessary ?
Please note, that the application on the different boxes only allow 20 sec difference in between them.
