Hi, James Thanks for pointing this. I think you're right. Let me confirm, so you're suggesting that we should just pass the TIMEOUT argument directly into OPENMCL-SOCKET:MAKE-SOCKET, like below? (defun socket-connect (host port &key (element-type 'character) timeout deadline nodelay local-host local-port) (with-mapped-conditions () (let ((mcl-sock (openmcl-socket:make-socket :remote-host (host-to-hostname host) :remote-port port :local-host (when local-host (host-to-hostname local-host)) :local-port local-port :format (to-format element-type) :deadline deadline :nodelay nodelay :connect-timeout timeout))) ; here (openmcl-socket:socket-connect mcl-sock) (make-stream-socket :stream mcl-sock :socket mcl-sock)))) Regards, Chun Tian (binghe) 在 2010-1-4，02:10， james anderson 写道：

good evening;

in the openmcl backend, socket-connect[1] converts the timeout value to internal runtime units, but (at least for a tcp connection) the respective ccl operator[2] intends to convert from seconds to milliseconds
