Hi !

I have trouble logging to the website with the pop-up
" The server's security certificate is not yet valid! "

I believe this cause by not having the proper " date & time " settings... but I still have problem of changing " date & time " because the pop-up will display

" You do not have the proper privilege level to change the system time "

This is my Personal Computer and logging as administrator. Sometimes, I can change the date & time, and many times cannot.

During the time when I can change the " date & time " , the " The server's security certificate is not yet valid! Problem is solved! but then it will repeat again and again when I use my PC.

Please. Help to fix this one.

Thank you guys!

If you're logged in as an admin, and cannot access the system time, then it sounds like a virus or malware. You can try opening it from a command prompt:

Start -> run -> cmd
In the black window type:

Runas /user:administrator timedate.cpl

Type in the admin password, and it should open. If that doesn't work you may need to change it in gpedit

Start -> run -> gpedit.msc

Under computer configuration expand Windows Settings -> Security Settings -> Local Policies -> select User Rights Assignment. Make sure "Change the system time" and "Change the time zone" have the account you are using listed. Hope this helps.

After I saw the change the sysem time, what is the next step?

Try changing the system time with the admin account or give admin privileges to your user account.
