How can I set the format for the ${date} variable which can be used in Eclipse templates?
You could tell Eclipse to use a specific locale different from that of your operating system. Eclipse 3.5 (64 bit) doesn't use the MacOS X region setting. MacOS X english installation language with Germany as country provides a wrong date format.
You can fix it for your Eclipse installation when you append following lines to your eclipse.ini:
-Duser.language=de
-Duser.region=DE
