[tz] I found a bug in tzdata2014f.tar.gz for Europe/Moscow or similar such as Europe/Volgograd

Azhar,

What is the result when you run the following?
$ zdump -vc 2014,2015 Europe/Moscow

Do you see the expected transition reflected in that output, like this?
Europe/Moscow  -9223372036854775808 = NULL
Europe/Moscow  -9223372036854689408 = NULL
Europe/Moscow  Sat Oct 25 21:59:59 2014 UT = Sun Oct 26 01:59:59 2014 MSK
isdst=0
Europe/Moscow  Sat Oct 25 22:00:00 2014 UT = Sun Oct 26 01:00:00 2014 MSK
isdst=0
Europe/Moscow  9223372036854689407 = NULL
Europe/Moscow  9223372036854775807 = NULL

Since your zdump output prints "UTC" instead of "UT", it looks like you're
using a zdump version before 2013e.  So you might be using older data than
you think, too; the Russian transition for 2014-10-26 is present in 2014f
and later.
