How to get current time and date
Getting the current time and date involves Syscon scratchpad and Syscon command 0x11. Syscon command 0x11 returns twice the number of seconds Syscon has been running since its power on. Syscon scratchpad contains at offset 0x10 the timestamp when Syscon "started" running. It is stored in the following format: microseconds since 01/01/0001 and divided by 2^19. By adding those values together, the OS obtains the current time and date.
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)
