How to keep the system time between reboots?

Hello.

I want to keep the system time between reboots (Obviously not in case of power failure).
Is there any chance without an external real time clock chip?
... if not ... is there any RAM region that is not reset between reboots?

Thanks.

Alternative Bluetooth/BLE Stack.

Is there any alternative bluetooth stack ported to esp32?
Bluedroid is very convoluted and undocumented.

I have found free BLE stacks like Zephyr and Mynewt but I have not enough skills to port them.

Thanks.
