Ok then the issue is deeper then the time being off. It seems your OSX system is not updating your time correctly. Follow the steps below or accept the remote proposal so i can do it for you :)
In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. Then select the keychain access application.
In the upper left corner of the window, you should see a list headed Keychains. If not, click the button in the lower left corner that looks like a triangle inside a square.
In the Keychains list, there should be items named System and System Roots. If not, select
File then Add Keychain
from the menu bar and add the following items:
Open the View menu in the menu bar. If one of the items in the menu is
Show Expired Certificates
select it or it will show
Hide Expired Certificates
which is what we want.
From the Category list in the lower left corner of the window, select Certificates. Look carefully at the list of certificates in the right side of the window. If any of them has a blue-and-white plus sign or a red "X" in the icon, double-click it. An inspection window will open. Click the disclosure triangle labeled Trust to disclose the trust settings for the certificate. From the menu labeled
Secure Sockets Layer (SSL)
no value specified
Close the inspection window. You'll be prompted for your administrator password ***** update the settings.
Now open the same inspection window again, and select
When using this certificate: Use System Defaults
Save the change in the same way as before.
Revert all the certificates with non-default trust settings. Close application then click the apple icon and select restart.
