nRF9160 > AT+CCLK time difference 2hours

[Oleh]

Dear Team,

why is that the command "AT+CCLK" returns time with 2hours of difference? How should one compensate?

AT+CCLK?
+CCLK: "19/07/19,19:57:30+08"
OK

AT+CCLK?
+CCLK: "19/07/19,19:57:58+08"
OK

// current local time is: 21:59 now 

thank you and best

Hi.

The AT+CCLK? returns GMT time, and the difference to local time in quarters of an hour.

If you divide your difference (8) by 4 you get 2 hours.

Best regards,

Didrik

Hi.

You can use the modem_info library to get the time, as well as other information from the modem.

Best regards,

Didrik

Hi Didrik,

I have cloned the head from git (2019-11-04), made a sample app, but the AT CMD = AT+CCLK does not return the date-time.

Nor it returns from the at-client. 

Am I missing something?

Here is the log:
