Description Karel Volný 2016-03-16 13:27:00 UTC

Description of problem:
tzdata upstream has decided to use UTC offsets for timezones instead of classic abbreviations - for example, "CEST" (= Central European Summer Time) would become "+02"
(so far this hasn't been applied for already existing zones like the above example, just for newly created, see below for one of them)

unfortunately, such naming is unexpected by many tools, zdump being one of them

Version-Release number of selected component (if applicable):
glibc-common-2.17-106.el7_2.4

How reproducible:
always

Steps to Reproduce:
1. update to tzdata-2016b
2. zdump -v Europe/Astrakhan >/dev/null

Actual results:
zdump: warning: zone "Europe/Astrakhan" abbreviation "+03" lacks alphabetic at start

Expected results:
(no output)
