how to set the time?

Hello, set_time(1387188323); Set RTC time to 16 December 2013 10:05:23 UTC how can we set the time? what is the relation between (1387188323) to 16 December 2013 10:05:23.

If you want an easier way to set or read the time on the Nucleo Boards I would suggest looking at Kenji's page: https://developer.mbed.org/users/kenjiArai/ and https://developer.mbed.org/users/kenjiArai/code/RTC_w_COM/

It is the Unix-Time. For more Information look at [https://en.wikipedia.org/wiki/Unix_time]

Depending on how you want to use the RTC function with the Necleo boards, there are some considerations.

The RTC does work correctly on the boards I have if the crystals and loading capacitors are fitted, HOWEVER if the MCU is reset the RTC time registers are reset. This will happen with or without a 3v back cell connected to RTC Vin.

This renders the platform useless for true RTC functionality.

Use Unix Time Convertor.
