Detailed Description

Structure for storing date and time values with sub-second precision.

The structure is 1-1 mapped to the struct tm for the members tm_sec to tm_isdst making it compatible with the standard time library.

Note
Use rtc_time_to_tm() to safely cast from a rtc_time pointer to a tm pointer.
