getTimeNowMs()

efitimems_t getTimeNowMs

(

)

Returns the 32 bit number of milliseconds since the board initialization.

32 bit return type overflows in 23(or46?) days. tag#4554. I think we do not expect rusEFI to run for 23 days straight days any time soon?

64-bit result would not overflow, but that's complex stuff for our 32-bit MCU
