INITTODR(9) Kernel Developer's Manual INITTODR(9)

inittodrinitialize system time

inittodr(time_t base);

The () function determines the time and sets the system clock. It tries to pick the correct time using a set of heuristics that examine the system's battery-backed clock and the time reported by the file system, as given in base. Those heuristics include:

Once a system time has been determined, it is passed to the () function.

The inittodr() function prints diagnostic messages if it has trouble figuring out the system time. Conditions that can cause diagnostic messages to be printed include:

microtime(9), resettodr(9)

Each system's heuristics for picking the correct time are slightly different.
