RTC Time on board

[FABLAB-LH]

Hello,

The datasheet of the board tells that we can get RTC Time by the Command AT (AT+CCLK?) and set by (AT+CCLK="18/12/12,17:53:00+01").
Do you plan to develop this feature in your library?
Thank 's you.

I bought several units of the HAT but I can't make the RTC work. Even with the backup battery installed, the clock resets to 04/01/01,00:00* when the power is disconnected. Did you get any luck in making the RTC work?
