I find it difficult to understand you.

But the input I can not change:
>SELECT 
>to_char(CONVERT_TO_UTC( '2011-03-22 14:17:00+01'::timestamptz
,'CET'),'yyyy-mm-dd hh12:MI:SS') AS winter, 
>to_char(CONVERT_TO_UTC( '2011-04-22 14:17:00+02'::timestamptz
,'CET'),'yyyy-mm-dd hh24:MI:SS') AS summer; 

The system must know alone when is summertime and when is wintertime. Can it
this?
