Real time clock.

Reading the current time and date involves the Syscon scratchpad and a Syscon command (0x11) that returns 2 * the number of seconds the Syscon has been running. The scratchpad value contains the timestamp when syscon "started" running, so if you add those together you obtain the current time. In pseudocode: 

last_reincarnated_tick = syscon_read_scratchpad(offset=0x10, size=5)
up_time_half_seconds = syscon_cmd_read(cmd=0x11, size=4)
UTC = timedelta(microseconds=last_reincarnated_tick * (1<<19)) + datetime(1,1,1) + timedelta(seconds=up_time_half_seconds*2)
