Controller PM 867 (172.16.4.1) is synced with ASCS1(172.16.4.21 Enabled NTP server). This controller is CM for other controllers, I have read in AKs threads that in this type of sync schemes Time Adaptor should be disabled in Connecticity Server.
If the AC 800M Time Adapter is installed by mistake, and it needs to be removed: 1. Select: Start > Control Panel. 2. Select Add or Remove Programs. 3. Select: AC 800M Connect > Change/Remove. 4. Select Modify and disable Time Adapter. When Modify is selected, the check boxes indicate the selected features and not the installed features. Example: if the Time Adapter has been uninstalled, the next time Modify is selected, the check box for the Time Adapter will be enabled even if it is not installed. The default features that are enabled when selecting Modify are the same as when selecting Typical for a new installation.
Just a Additional note for future. Now in 800xa 6.1 Under The Time Service at the Group they have added a New Configuration tab that allows you to Select a Specific Time Adapter or Even Disable one. See 6.1 Network Configuration Manual Pg 199 3BSE034463-610 A
