* Name: stm32_rdtime

* Description:
* Implements the rdtime() method of the RTC driver interface
*
* Input Parameters:
* lower - A reference to RTC lower half driver state structure
* rcttime - The location in which to return the current RTC time.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned
* on any failure.
