This takes 3 arguments, which are the following structure packed into 12 bytes (no padding): | |||
s32 year; | |||

This should be the current date/time (AgbBg seems to get it from MCU); it's converted from this structure into milliseconds, and saved into .data. Another .data variable is set from svcGetSystemTick by this command, and another function in (LGY) P9 essentially does <code>return date_time_set_from_this_command + ticks_to_ms(svcGetSystemTick() - systemtick_from_this_command);</code> to get the current date&time. | |||
