NTP Issue

NTP server or SC seems to have a big problem. I noticed large changes to the system clock yesterday. I checked the SC message log and found that NTP client was making changes as much as 11 seconds to my system clock every few minutes. I turned off NTP client and used Windows Time Sync to set the time and left NTP client off over night. This morning my system clock was still synced with Windows Sync. I restarted NTP client and it immediately starts to change the system clock again.

Attached is a screen shot to the message log.

Update: I performed an update to v2848 yesterday. I just rolled back to v2807, and the clock adjustments look more reasonable. With the exception of the first few. Still not sure I trust the NTP time sync at this point.

Attached is another screen shot of v2807 message log.

Update: Back to v2848 same issue

I have polling set to 30 seconds. How can my system lose or gain 2 seconds in that 30 second interval?
