[SUMMARY]: NTP and BIG time difference

Wow - close to 30 responses! Thanks folks

1. Run ntpdate to set the date correctly, and start xntpd running on the
server to handle minor drift. ntp by itself won't handle a 25 minute
differential.

2. Dave Harrington also pointed to a useful article regarding this
very topic:

Read Sandra Henry-Stocker's Notes:

She's a great reference for practical information. This just happened to be
her latest column.

3. The biggest caveat is to ensure that the applications you have
running on your server (e.g. databases such as Oracle) are not impacted
adversely by time stamps jumping backward in time all of a sudden.

4. A reboot is not necessary

Thanks once again

I just checked one of our V880 servers and noticed it is a whole 25
MINUTES fast. needless to say, I didnt have ntpd installed. Would NTPD
correct such a huge difference upon activation or should the system be
rebooted and the system clock reset first?

Thanks

Scotty
