Shorten the timeout for openssl s_client?

[Todd Thatcher]

All, 

   Using the command  "openssl s_client -connect gmail.google.com:443"
openssl gets the certificate information and stays connected until I
enter QUIT, or the timeout is hit -- about 2 minutes later.   I want to
script  certificate expiration date checks for out servers. Is there a
command-line switch or some other advice that I can use to change this
behavior?  

 

Thanks in advance
