OK, CET is bad example. But it is the same with WAT (I use in examples
too) and is is not on the 'blacklist'.

So add please WAT (and may be some more 'obsolete' timezones) to the
blacklist.

For local time it works as everyone expecting. Automatic handling of
normal/summer time is simply great.

But I still don't know how to set input timezone to UTC+n (when I have
to use such 'bad' timezone) without searching for some place where they
use such time offset from UTC I need for the whole year. The searching
is strange and tend to generate errors (for some states is used timezone
 political decision and it could change).

I miss in all answers before what I get in the last answer. Something
like 'continent/location type is preferred and the others are only
because backward compatibility' Please use only continent/location, the
rest could behave unexpectedly. And it's all. If this will be in the
documentation (if is this true) it will be enough. But here is still
question I have in previous paragraph.

There is no wrong design here. Every area has very specific rules about
which GMT offset there currently is, and also what it was in the
present. This is why we support  500+ different areas like you can see
in our documentation:
http://no2.php.net/manual/en/timezones.php
So yes, you *do* need the timezone name, and not CET for example. There
are abbreviations that are ambiguous (like EST) so they are *not* safe
to use. Please don't lecture us on how this should work.

The CET ones you are mentioned are marked as "do not use" on this
documentation page:
http://no2.php.net/manual/en/timezones.others.php

Once again.

I have data (time is in CET timezone whole year). So why when I set by
date_default_timezone_set() CET, function returned me UTC+2 (ie. CEST)
when some palces in CET timeznoe are using CEST. I don't need
continent/location definition, because when I set CET it is UTC+1
(please read some further docs about timezones). So returning CET/CEST
depending on date is wrong because CET != CEST.

I know how have I do some 'walk around'. But when I have to try some
places if they are in the right timeznone (or the right UTC+n) and use
summer time or not it's stupid and wrong. And all because some really
intelligent people implemented some strange 'intelligence' into PHP
time/date functions.

UTC+x are there just for you convenience.
- no, this is because it shows clear relations between different
timezones.

Notice: date_default_timezone_set()
[function.date-default-timezone-set]: Timezone ID 'UTC+1' is invalid 
Notice: date_default_timezone_set()
[function.date-default-timezone-set]: Timezone ID 'GMT+1' is invalid

So how to set default timezone to UTC+1 ???

Result: it is not bug, it is wrong deign, but how to write bug report
about wrong design?

UTC+x are there just for you convenience.
If that's NOT what you need, use the correct name of the timezone you
need.

In documentation you provide continent/location for setting timezone
(in documentation $timezone_identifier)

You are able set timezone by timezone code (UTC, WET, CET, etc.).

This timezone is defined like distance form UTC (ie. CET = UTC+1).

It's strange to accept UTC+2 for dates when some places in current
timezone has summer time (for CET it's CEST) because some countries
don't have summer time (Algeria has CET, but they don't have any CEST).
So add this type of intelligence into functions is simply bad. For
getting correspondent local time is continent/location and not shifting
timezones.(CET != CEST)

May be CET is not the best example. Better is WAT. Only one country use
summertime and PHP is automatically returning WAST...

Solution:
- add description of this behaving into documentation (easiest way) or
- handle timezones like UTC+n, so add summertime codes, because now
setting CEST fails.

Please let me know if miss something.

Please explain what exactly you think is wrong.
I don't understand a word from your description.
A short reproduce case with expected and actualy values would help a
lot.
