Setting The Date Backwards

Anthony_69 — Fri, 14 Nov 2003 10:37:38 GMT

Hi,

I currently have a data sensitive live HP UX system that is running at approximately 5 minutes ahead of what it should be.
Can someone advise me of the safest way to change the time backwards?

Thanks

Hi,

I would suggest setting up the NTP protocol to keep the time in sync.

Hi Anthony,

Use the date command as follows:

date -a -300

This will slowly slew the time backwards five minutes
NOTE the negative value on seconds.
This will not make time go backwards literally, it slows the the actual seconds until the slew value is reached. Perfectly safe.
Then you need to get an NTP server set up to keep time in line.

HTH,
Jeff

Thanks guys. Seems to be working a treat. I did have it talking to an NTP server, however said server decided to go to sleep over the past couple of weeks

Hi (again) Anthony,

300 seconds should take 2-4 hours to accomplish, so be patient.

Rgds,
Jeff
