In a similar fashion, people use GMT to mean both GMT and BST (British 
Summer Time, UTC+1) for Europe/London, notably, Google Calendar. The 
amount of confusion that causes is staggering, especially among my 
American co-workers scheduling meetings. I'd strongly suggest you use 
CET for UTC+1 and CEST for UTC+2 exclusively.
