+.Dt TIMESPEC_GET 3
+.Os
+.Sh NAME
+.Nm timespec_get
+.Nd get current calendar time
+.Sh SYNOPSIS
+.In time.h
+.Ft int
+.Fn timespec_get "struct timespec *ts" "int base"
+.Sh DESCRIPTION
+The
+.Fn timspec_get
+function sets the interval pointed to by
+.Fa ts
+to hold the current calendar time based on the specified time base in
+.Fa base .
+.Pp
+The base
+.Dv TIME_UTC
+returns the time since the Epoch.
+This time is expressed in seconds and nanoseconds since midnight (0 hour),
+January 1, 1970.
+In
+.Ox ,
+this corresponds to
+.Dv CLOCK_REALTIME .
+.Sh RETURN VALUES
+The
+.Nm
+function returns the passed value of
+.Fa base
+if successful, otherwise
+.Dv 0
+on failure.
+.Sh SEE ALSO
+.Xr clock_gettime 2 ,
+.Xr gettimeofday 2 ,
+.Xr time 3
+.Sh STANDARDS
+The
+.Nm
+function with a
+.Fa base
+of
+.Dv TIME_UTC
+conforms to
+.St -isoC-2011 .
+.Sh HISTORY
+The
+.Fn timespec_get
+function was ported from
+.Nx
+and first appeared in
+.Ox 6.5 .
