PostgreSQL get results in current time zone - sql

Question

as said in the title I would like to have a query that returns the value of the time stamp in my current time zone (even according summer time!).
my_table is:
|timestamp|name|value|property1|property2|
|---|---|---|---|---|
|2021-08-01 00:00:00+00|10|0.44|0|0|
|2021-08-01 00:05:00+00|15|0.76|0|0|
|2021-08-01 00:10:00+00|12|0.28|0|0|
(Don't ask me why I cannot put this table directly in markdown...prob cause the dates)
Now for example if I have to select the 24h corresponding to the entire day in my time zone at the moment my solution is:
SELECT timestamp AT TIME ZONE 'CEST',name,value
FROM my_table
WHERE name IN (10,11,12)
AND timestamp BETWEEN '2021-08-01 00:00:00+02' AND '2021-08-02 00:00:00+02'
ORDER BY timestamp DESC
As you can see there is a problems here:
I have to specify every time if I is CEST or CET (now is CEST here)
and then I have to add +02 at the end of the dates (or +01 in CET)
There is a way to avoid this conceptual repetition?? any suggestion even to improve the query is appreciated
the command SELECT version(); gives me back PostgreSQL 12.7

Set your session's timezone appropriately.
set timezone TO 'Europe/Berlin';
select '2021-08-01 00:00:00+00'::timestamptz;
timestamptz
------------------------
2021-08-01 02:00:00+02
select '2021-12-01 00:00:00+00'::timestamptz;
timestamptz
------------------------
2021-12-01 01:00:00+01
select '2021-08-01 00:00:00'::timestamptz;
timestamptz
------------------------
2021-08-01 00:00:00+02
What is your session timezone set to now?
