Your license could not be activated : License File Expired

I had a issue with cPanel license as I was getting the error "Your license could not be activated"

Solution >>

I tried

/usr/local/cpanel/cpkeyclt

but the issue didn't get resolve. then I cheked the date on the sever and found that very old date was set on the server. Simply I sync the date with the command :

rdate -s rdate.cpanel.net

The issue got resolved.
