It doesn't eliminate the need for monitoring. I'm looking for a program that is going to connect to all my SSL sites, and report back a problem if the cert is within 30 days of expiration. It is easy enough to write a client that will fail after the cert has expired, but I want one that will warn me ahead of time. And I don't want to mess with the system clock or something like that. It shouldn't be a big program, I may just write it myself.

Depending on your use case, environment, etc there are existing tools like Monit that can do this for free. Or paid services like Uptime Robot and StatusCake.

Nagios can do that (and you could borrow from its check_http) define command { command_name check_certificate command_line $USER1$/check_http -H $ARG1$ -p $ARG2$ -4 -S -C 21 -t 20 --sni } A bigger challenge is getting a complete list of your https websites, and an even bigger one is finding and monitoring all those non-https certificates, eg payment gateway certificates.

updown.io https://updown.io/ https://updown.io/ has a pretty generous free tier and (in addition to checking if your service is up) sends you a warning when a cert is expiring within 14 days

https://sslping.com https://sslping.com is totally free, superfast and checks your TLS settings too (it's my baby)
