Build size and comparison to main:

While were at it changing stuff related to Date & Time, we could also consider this PR:

#1782

Yeah, const-correctness in C++ isn't very obvious haha. I'm not by my dev kit so I can't debug this, but it really doesn't seem to like calling SetTime in the constructor, as doing so seems to result in a non-booting firmware.

Ah, that would be as system task doesn't exist yet so it hits a null ptr deref when it tries to push OnNewTime

Edit: I think just adding a systemtask null check should suffice?

Good thinking! Adding a NULL check should indeed fix it.

It boots now, but I haven't been able to get the time to not be read from .noinit 😅, so I can't test if it actually works. I'm sure if the battery runs out it'll reset the time (isn't it annoying having such good battery life!)

Is it possible to make a Firmware that always reads the noinit data I instead of the filesystem?

So I tried @pipe01's InfiniEmu and it looks like we're off by a little bit. I'd guess the month and day are meant to be ones

That makes a lot of sense haha.

My watch just ran out of battery, so I can confirm: this does work on actual hardware!
