3-1-3. Time Configuration 
 
The GSM Series switches provide two methods to keep the switch’s time settings correct, they 
are via manual input and via a Time Server on the internet. If you are manually entering your time 
settings enter the “Year”, “Month”, “Day, “Hour”, “Minute” and “Seconds” into the space provided. 
If you enter a number that is invalid, for instance you enter 61 in the seconds field it will be 
rounded down to the nearest valid number, in this case 59. 
If you are using NTP (Network Time Protocol) there are four built in Internet Time Servers that 
you can use, or there is a space provided where you can enter a particular Time Server address. 
When using NTP you will also need to specify what time zone you are presently located in. The 
Time Zone is Greenwich-centered which uses the expression form of GMT +/- xx hours.
