From that function's comments:

// This function is called by WinCE OS to initialize the time after boot.

So how about calling it:

init_time

or maybe

init_time_after_boot

The reason it's not calleld init_time_after_boot - well, first of all Microsoft coding standards call for CamelCase. But secondly, there are several "times", and there are several ways to "initialize" something, and there are several meanings to "boot."

You're either going to have a naming conflict, or you're going to have a bunch of idiots who wanted to initialize a different clock, who start posting to forums saying "i don't understand???! i called init_time waht's wrong???"

Sure, they could call it

SendTheIOCTLCommandToInitializeTheRealTimeClockForTheOEMAbstractionLayer

but sometimes the names of functions are going to be ugly.

OAL is "OEM abstraction layer" and IOCTL probably means that the RTC is set by sending an IOCTL command.
