There is a little bug in WHM "server time".
When you click on "Sync Time with Time Server" the top of the frame will show you "Time has been synced" regardless of the response from the host or if there was even a connection.
Cpanel team, this needs to be changed!
So if you do not see a response like this:

rdate: [] Fri Aug 1 22:59:04 2003

then your date and time has not been updated! Support Ticket Number:
