-For time-based options, use `set_socket_opt_time` from the `detail` namespace:
-
-```cpp
-httplib::detail::set_socket_opt_time(sock, SOL_SOCKET, SO_RCVTIMEO, 5, 0); // 5 seconds
-```

 > [!TIP]
 > For most use cases, prefer `set_tcp_nodelay(true)` or `set_socket_options(callback)` on the Server/Client instead of calling `set_socket_opt` directly.
