resettodr – set battery-backed clock from system time

SYNOPSIS DESCRIPTION SEE ALSO BUGS

#include <sys/types.h>

#include <sys/systm.h>

void
resettodr(void);

The resettodr() function sets the system's battery-backed clock based on the contents of the system time variable.

On many systems, resettodr() has to convert from time to a time expressed in terms of year, month, day, hours, minutes, and seconds. Many of the implementations could share code, but do not.
