But why it returns mean solar time?
After changing of timezone to Europe/Kiev, time on site offsets on +2 hours,
and it is obvious, that I expect to obtain the same value in returned array,
but observe such unexpected behaviour (who needs this?).
So, if this function returns mean solar time, how to get true time offsets for
each timezone correctly?

The documentation on this isn't very clear, but the array that is returned has
multiple timezones for most locations, organized by timezone abbreviation (ex
CET, GMT, PST). In this case, Europe/Kiev shows up under 7 different timezones
with offsets ranging from UTC+1 (no DST) to UTC+4. One of these is mean solar
time which, for Kiev, is UTC +7324 seconds (based on distance from 0 deg of
longitude). At 24hrs = 360°, 7324sec = 30.51667°E, which runs straight
through Kiev.

Function timezone_abbreviations_list() returns incorrect values of time offset.
For example, I live in Ukraine, Kiev (timezone Europe/Kiev) with time offset +2
hours, but function returns value, that equals to +2:02:04 (in seconds 7324),
similar problems are for other timezones.
Other cities in my country has the same offset +2 hours, but function returns
other values from interval +2 till +3 hours, why?
But functions, which works with time after changing of timezone return correct
values, so, the problem is only in this function.
