5.1.1 Setting the Time and Date
The WCM does not provide a non volatile Real Time Clock, instead it uses NTP to set the
date and time following power up. In applications where NTP is not available, the WCM
defaults to providing a simple uptime display.
To configure the NTP parameters, select the “Time and date” menu from the “System”
menu. The menu is as below:
Metrodata WCM3100 "" Alarms: Major
TIME & DATE
local Time 22:35:42
local Date Sat 1/1/2000
system up time 0d22h35m42s
time Zone GMT+0
NTP server 0.0.0.0
last sync never
Sync now
First CAPITAL - select item
<escape> - exit menu
If NTP is available, then the following parameters need to be set,
Time Zone +/-12
Since NTP uses GMT, time zone adjustment allows the
correct time to be configured wherever the units are
deployed globally.
NTP Server
Enter the IP address of the network NTP server.
According to the NTP protocol, the WCM will wait for a random period of between 1 and 5
minutes before requesting an NTP update.
If NTP is not available, then the user can manually enter the time and date, however since
these are non volatile and not maintained over a power cycle it is not recommended.
Additionally the system up time parameter is provided.
