getTimeNowLowerNt()

uint32_t getTimeNowLowerNt

(

)

Get a monotonically increasing (but wrapping) 32-bit timer value Implemented at port level, based on timer or CPU tick counter Main source of EFI clock, SW-extended to 64bits

2147483648 / ~168MHz = ~12 seconds to overflow

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?
