resettodr - set battery-backed clock from system time
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.
