On my machine I get this:

$ date -d 'Sun May  2 16:20:49 CEST 1999'
Sun May  2 16:20:49 BST 1999
$ date -d 'Sun May  2 16:20:49 CET 1999'
Sun May  2 16:20:49 BST 1999

Let's try something different:

$ date -d 'Sun Jan  2 16:20:49 CEST 1999'
Sat Jan  2 15:20:49 GMT 1999
$ date -d 'Sun Jan  2 16:20:49 CET 1999'
Sat Jan  2 15:20:49 GMT 1999

Interesting.
