    struct time_object *tobj;
    VALUE v;

    GetTimeval(time, tobj);
    v = rb_time_unmagnify_to_rational(tobj->timew);

        v = rb_Rational1(v);
    }
    return v;
}

Returns the value of time as a rational number of seconds since the Epoch.

Example

t = Time.now      #=> 2020-07-20 22:03:45.212167333 +0900
t.to_r            #=> (1595250225212167333/1000000000)

This method is intended to be used to get an accurate value representing the seconds (including subsecond) since the Epoch.
