RP5470 server time

[Ngoh Chean Siung]

Hi,

As at now, the RP5470 server (Pluto) time is 3 minutes faster that the standard Malaysian time.

Q1) What is the time variance over a period of year for RP5470? For example my casio watch stated that 1 year time variance is plus/minus 15 seconds.

Q2) Is it possible to delay the Pluto time of 3 mins over a fix period of time, says 1 week? This means that, we want to let HP-UX auto adjust the time to slow down in 1 week time. We can't change the time immediately due to our online transaction processing.

Pls advise.

Shalom Ngoh,

1)I've found HP-9000 servers can vary from time reality by up to 15 minutes a month. Generally its not that bad.

2) You should configure NTP and your box will suddenly keep peerfect time. NTP when connected to an accurate time source slighly slows or speed lock running time until synched.

If you cannot use NTP for some reason, you might want to use something like "date -a -180". This will automatically slow down the server's clock until it has "lost" the extra 180 seconds, then lets the clock proceed at normal speed. You can specify fractions of a second if necessary.

However, there is no way to control the speed of the time change. I used it once to correct a clock that was over 1 hour slow. I opened two "xclock -update 1" windows to monitor the process: one on a "reference server", the other on the server I was fixing. I used the "ntpdate -B" command to change the time, but the mechanism that handles the actual time correction is the same. As i recall, it took less than half a workday to get that server to correct time.

Hi,

What you mean is there is NO way to control how long we want to gradually adjust the time?

For your case, you used 'date' command to adjust the server time which is 1 hour server and it takes less than half day to complete. Do u observe the time adjustment when it is it process? Do u hv any idea of 1 min adjustment need how long to adjust?

regards.
