The above format is unclear to me. I look at timestamps every day, too
many, often change them.

I cannot understand what you mean.

If there is considered UTC time zone, then the only prefix for such
time stamp is +00 and nothing else, or no prefix at all.

The time stamps that specify UTC offset are expressed in local time,
not in UTC time. 

Here are few examples of ordinary usage of UTC offset converted to UTC:

2023-01-07 09:21:11.019166+03 which means: 2023-01-07 06:21:11.019166 @UTC
2022-10-05 14:09:04.79737+03 which means: 2022-10-05 11:09:04.79737 @UTC

Due to that ordinary usage of time stamps, something like @UTC+2 where
you specify 14:00 o'clock, is unclear, if you mean UTC time plus 2,
like 16 o'clock, or you mean 12 o'clock.

Time stamps having UTC offset are in their representation such as in
calendar tied to the time zone, as they maybe are derived from system
time, where time zone need not be displayed in the time stamp, but it
is nevertheless there and used by program to derive the UTC offset.

And it is either UTC time, or local time plus UTC offset.

There is no UTC time plus UTC offset, why would anybody need that as
time stamp?
