"If I set the clock back a week on the SmartCenter server I could log in fine. Once logged in if I tested the SIC communication I would get an SSL error referencing an expired SSL certificate on peer on all three of my enforcement points."

I'd guess this was because of the date mismatch between the SmartCenter (which you moved back a week) and the modules (which you didn't). Anyway, moving on.

"After revoking and attempting the recreate I am no longer able to log in to the dashboard if I set the clock back on the management server. I now get "the connection cannot be initiated... make sure <server> is up and running and you are defined as a GUI client""

If you create a new Cert with today's date and then move the date back a week, the cert won't be valid, since the date is before it's issue date. That might be your case. Anyway, if you are going to reset and do everything from scratch, please set the dates right on all devices.

What I would do:
1 - check SmartCenter version on the box
2 - check SmartCenter services are running
3 - check the SmartClient version you have on the client PC (GUI version)
4 - check you can reach the SmartCenter server from the GUI PC
5 - connect

If you have a firewall module running on the SmartCenter server you might need to unload policy

If this still fails you might want to check that the client PC is defined as a GUI client properly.

Hope that helps.
