No; given the proposed patch, Astrakhan has not observed DST since October 2010.
It just keeps changing its mind about its standard-time UTC offset.

This is a feature more than it is a bug. Too often we invent the tm_isdst flag:
that is, the flag is a property of tzdata that is in tzdata primarily because
the database format requires a value for it. In these cases it's better to avoid
propagating this invention into old-style time stamps like 'date' output in the
C locale. This sort of thing is rarely an issue in well-settled locales typical
of North America and western Europe, but it is a problem elsewhere, often in the
regions where we don't want to be inventing abbreviations either.
