How to sync real-time clock with network-time on BGS2T? | Telit Cinterion IoT Developer Community

Hello, I can imagine 3 ways to read current time using BGS2-T: 1. It is possible to read current time with at^sind command reading NITZ information, but remember that this feature is network dependent, so some networks won't support it. According to AT Spec the network usually sends a NITZ indicator when the mobile attaches to the network, when it enters a location area with different time zone or when a daylight change occurs. There are two ways to read NITZ data: A) Setup an +CIEV URC on NITZ update using commands AT^SIND="nitz",1 and enable URCs displaying with AT+CMER=3,,,2 B) Look up NITZ data with AT^SIND="nitz",2. Please be aware, that this data may be out of date as it is only updated in cases described above. To get additional information on NITZ please refer to "nitz" description of AT^SIND command in AT Spec. 2. As above solution is network dependent you can check local time and timezone by reading an sms sent to the module (the module can send an SMS to itself). See following example: at+cmgr=6 +CMGR: "REC UNREAD","+xxxxxxxxxxx",,"14/04/07,13:00:12+04" sms OK 3. You could use Socket Internet Service to query NTP server over GPRS to obtain current time. Hope you find my guidelines helpful. Best regards, Jedrzej Wiewiora
