How to get time from SIM900 ?

How to get current time using SIM900 ?

I am giving AT+CCLK? and it shows 01/01/01,00:00:07

There is a battery holder on my SIM900 modem. How to set up time once using an AT command ? I need to get time from network once and setup the time to SIM900.

I need to read time from SIM900 RTC or have to get current time from GSM network and send it as an SMS.

AT+CCLK= “YY/MM/DD,HH:MM:SS+02//// for setting time
AT+CCLK?//for getting time


Before you use "AT+CCLK?" command you have to use "AT+CLTS=1" for only once.
