SolutionSetting the time forward is usually OK.
However, slewing the clock to move 18-minutes is going to take some time (no pun intended). You might just step forward in one jump.
This aside, I hope that you are adjusting your clock in order for NTP to synchronize your server to an external time source.
Regards!

Re: Time change forward 18 minutes
A small test was showing this should take 15 minutes to adjust it forward 18 minutes. Knowing this it might be better to just do the jump.
Thank you for the help.

Re: Time change forward 18 minutes
Either shutdown the apps plus Oracle and make the change or reboot and set the time before Oracle starts. If you are using NTP, the reboot will jump the time before any apps start.

Re: Time change forward 18 minutes
I have tested date -a +420 and this took a few minutes local. Would date -a +420.100 take longer?

Re: Time change forward 18 minutes
The date command apparently slews the clock a *LOT* faster than ntp. The man page is silent about how fast this change is made as well as any side effects.

Re: Time change forward 18 minutes
this took nearly one hour to see the 18 minute avancement
I watched with . . .
while true
do
date
sleep 5
done
This reported ever 5 seconds with a 2 second advance each time but once in a while it would be a 2 second. This went without issues and was pleased withthe results.
Thanks for all your help and direction

Re: Time change forward 18 minutes
It is best to down Oracle DB before change any system time forward or backward.Because it will effect on your ONLINE Database.
You can use date 032316552010.
#date MonthDateHourMinutesYear
You can forward 18 minutes from your present time. It will effect immediately.
Thanks
