+.Sh NAME
+.Nm ts2timo
+.Nd convert time interval to tick count
+.Sh SYNOPSIS
+.In sys/timevar.h
+.Ft int
+.Fn ts2timo "clock_id clock_id" "int flags" "struct timespec *ts" "int *timo" "struct timespec *start"
+.Sh DESCRIPTION
+The
+.Fn ts2timo
+function converts the time interval specified in
+.Fa ts
+into the integral number of system ticks that would elapse (including the
+current tick) and places the result in
+.Fa timo .
+The interval type is specified in the
+.Fa flags
+argument and can be either
+.Dv TIMER_ABSTIME
+or
+.Dv TIMER_RELTIME .
+If the interval is specified as an absolute time, then the
+.Fa clock_id
+clock is used to convert it to a relative time.
+If the
+.Fa start
+argument is not
+.Dv NULL ,
+then current time for the
+.Fa clock_id
+clock is placed in that argument.
+.Sh RETURN VALUES
+On success
+.Fn ts2timo
+returns
+.Dv 0 .
+On failure it returns
+.Er ETIMEDOUT
+if interval computed was
+.Dv 0
+or negative, and
+.Er EINVAL
+if
+.Fa ts->tv_usec
+field in the computed interval is out of range, or the
+.Fa clock_id
+argument is invalid.
+.El
+.Sh SEE ALSO
+.Xr clock_gettime 3 ,
+.Xr clock_nanosleep 3
+.Sh HISTORY
+The
+.Nm
+function first appeared in
+.Nx 7.0 .
