.Sh NAME
.Nm resettodr
.Nd set battery-backed clock from system time
.Sh SYNOPSIS
.In sys/types.h
.In sys/systm.h
.Ft void
.Fn resettodr "void"
.Sh DESCRIPTION
The
.Fn resettodr
function sets the system's battery-backed clock based on the contents
of the system
.Va time
variable.
.Sh SEE ALSO
.Xr inittodr 9 ,
.Xr time 9
.Sh BUGS
On many systems,
.Fn resettodr
has to convert from
.Va 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.
