TIMESTAMP / summertime

Hello,

I *detest* British summertime. This year it took me two days to adjust.
Now I am realizing that my program might need some adjusting too:

Joking aside, I need some advice regarding TIMESTAMP colums and I can't
quite get my head round this at the moment:

I created a table TRANSAKTION with a TIMESTAMP column without qualifying
"with/without time zone".
My understanding is that this is equivalent to "TIMESTAMP without time
zone"? (I am using Postgres 7.4.)

I am accessing the database via a Java client program. The DB access
code is generated by an O/R mapper. Client and server are in the same
timezone.

One of the things I need to do select records from TRANSAKTION, which
fall within a certain time period, specified in days: e.g. 1st Mar 2005
to 31st Mar 2005. In other words, I want to grab TRANSAKTIONs >= 1 Mar
00:00 and < 1 Apr 00:00.

The generated WHERE clause is:

WHERE (TRANSAKTION.THE_TIME>={ts '2005-03-01 00:00:00.0'} AND
TRANSAKTION.THE_TIME<{ts '2005-04-01 01:00:00.0'})

Should it be '2005-04-01 00:00:00.0' or 2005-04-01 01:00:00.0' ??

Also, in autumn, when the clocks go back, I need to be able to
distinguish between the two double hours.

Sorry, if I sound confused. Unfortuantely, this is what I am ;-)
