Possible improvement: get the current time from internet on reset

Using this example for timing instead: https://www.instructables.com/Command-Line-Assembly-Language-Programming-for-Ard-3/

Change back to 40b08a67c034a109a4cb00b98818a32f7fb26b43 version where timer_ticks are stored in dseg if you run out of registers. Slower as values are loaded from data memory more often but more consistent code and less registers used.
