.Sh NAME
.Nm resettodr
.Nd set battery-backed clock from system time
.Sh SYNOPSIS
.Ft void
.Fn resettodr "void"

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,

to a time expressed in terms of year, month, day, hours, minutes,
and seconds.
Many of the implementations could share code, but do not.
