Once you are syncronized with your time server the manual field is filled with the current date and time. check under the time server address for the word Syncronized if you don't see it your AP has not been able to reach the time server.
also be sure to check the Event log configuration and select the time format. you will probably want to select local for the time stamp display.
Thanks for your response. I found that the NTP server I was pointing to was not an "Authorized" server and the time never syncronized. I pointed to an authorized server and the time sync'd. Thanks again for pointing me in the right direction.
