Chapter 25: Network Time Protocol Server

Enabling Or Disabling A Network Time Protocol (NTP) Server

Psion Teklogix 9160 G2 Wireless Gateway User Manual

25.2

Enabling Or Disabling A Network Time Protocol (NTP) Server

To configure your access point to use a network time protocol (

NTP

) server, first 

enable

 the 

use of NTP, and then select the NTP server you want to use. (To shut down NTP service on 
the network, disable NTP on the access point.

25.3

Updating Settings

To update time settings:
1. Navigate to the 

Time

 tab page.

2. Configure the time settings as required.
3. Click the 

Update

 button to apply the changes.

Table 25.1  NTP Settings

Field

Description

Local Time

The current local time is shown at every update.

Network Time Proto-
col (NTP)

NTP provides a way for the access point 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. 

For more information on NTP, see 

http://www.ntp.org

. 

Choose to either enable or disable the use of a network time protocol (NTP) server:

• To enable the NTP server, click 

Enabled

.

• To disable the NTP server, click 

Disabled

.

NTP Server

If NTP is enabled, select the NTP server you want 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.

Time Zone

A list of time zones (for instance, “EST (-05:00)”) is presented on the drop-down list, along with the 
choice of setting your own customized value. If 

Custom

 is selected, two textboxes appear next to the 

select box, where you may enter your choice of abbreviation and offset from UTC. Custom offset 
from UTC is given as hours and minutes east of UTC. For instance, -0800 is eight hours west of UTC 
(i.e. Pacific Standard Time), while +0930 is nine hours, thirty minutes east (i.e. Australian Central 
Standard Time).

Daylight Saving Time adjustments are not available.
