Time Settings

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.

See http://www.ntp.org/ for more information about NTP.

To configure your AP to use a network time protocol (NTP) server, first enable the use of NTP, and then identify the NTP server you want to use.

Field	Description
System Time	Shows the current system time.
Set System Time	NTP provides a way for the AP to 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. Choose to set the system time by either using a network time protocol (NTP) server or setting it manually: To permit the AP to poll an NTP server, click Using Network Time Protocol (NTP). To set the system time manually, click Manually.
NTP Server	This field appears when you select Using Network Time Protocol (NTP) in the Set System Time field. If using NTP, specify the NTP server to use. You can specify the NTP server by host name or IP address, although using the IP address is not recommended as these can change more readily.
System Date	This field appears when you select Manually in the Set System Time field. Use the System Date list to select month, day, and year.
System Time (24 HR)	This field appears when you select Manually in the Set System Time field. Use the System Time list to select hours and minutes. All times are relative to the local time zone.
Time Zone	Select the international time zone in which the AP is operating, for example USA (Eastern).
Adjust Time for Daylight Savings	Select the Daylight Savings option to adjust the system time for Daylight Savings Time (DST). Fields appear in order to select the date and time to start and end DST.
DST Start (24 HR)	Use this field to configure Daylight Savings Time to start. The start time is relative to standard time. If the starting month is after the ending month, the system assumes that you are in the southern hemisphere. From the week list, select the week of the month (First, Second, ..., Last). From the day list, select the day of the week (Sunday, Monday...). From the month list, select the month (January, February...). Specify the time (24-hour format) by selecting the hours and minutes.
DST End (24 HR)	Use this field to configure Daylight Savings Time to end. The end time is relative to Daylight Savings Time. From the week list, select the week of the month (First, Second, ..., Last). From the day list, select the day of the week (Sunday, Monday...). From the month list, select the month (January, February...). Specify the time (24-hour format) by selecting the hours and minutes.
DST Offset (minutes)	From the DST Offset list, select the number of minutes to add during Daylight Savings Time (15 to 120 in 15-minute increments).

Note: After you configure the Time settings, you must click Apply to apply the changes and to save the settings. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low.
