Enabling the Network Time Protocol
The Network Time Protocol (NTP) is an Internet standard protocol that 
synchronizes computer clock times on your network. NTP servers transmit 
Coordinated Universal Time (UTC, also known as Greenwich Mean Time) to their 
client systems. NTP sends periodic time requests to servers, using the returned 
time stamp to adjust its clock. The timestamp is used to indicate the date and time 
of each event in log messages.
By using NTP, the AP can obtain and maintain its time from a server on the network. 
Using an NTP server gives your AP the ability to provide the correct time of day in 
log messages and session information. 
See
 for more information about NTP.
To configure the NTP that the access point uses manually as shown in 
 or by using a server as shown in 
, click the Time
 
tab and update the fields as described in
