Issue
The following is a typical entry in a controller error log:
184 I 01/07/2012 16:02:16.19 0x00010000 0x0021a600 0x00177b9a 0x00000000 0x00000136

Cause
The above entry is an indication of a clock change in the controller.
Resolution
184 I 01/07/2012 16:02:16.19 0x00010000 0x0021a600 0x00177b9a 0x00000000 0x00000136
The above entry is just an informational log entry - not an error. This can be seen by the "I" after the line number 184.
The three types of entries in the controller error logs are:
- 'I' (Informational)
- 'W' (Warning)
- 'E' (Error)
It is not unusual to see the Clock Change entry a few times a day as many sites are set up with a time sync program that runs in one workstation every hour and synchronizes the WS time to the lowest ID network level controller in each network object.
In this case there were dozens of entries per hour as there was a looping time sync program updating the clock whenever the time difference was >1 sec.
For a program to sync time, see Time sync controllers to workstations.
