Please change this to WONTFIX.  The confusing entries are part of the
upstream tz database, and they've been there 20 years or so.  They are
present only for backward-compatibility reasons for decades-old usage,
which are discussed in the "etcetera" file of the tzdata distribution.
The confusing entries should not be used by new applications, and are
not likely to change in the future (unless they're simply removed
entirely).

Title:
  timezone selections in ETC are confusing / inverted

Status in “tzdata” package in Ubuntu:
  New
Status in “tzdata” package in Debian:
  New

Bug description:
  Looks like GMT[+-}<number> timezones have signs swapped.

  My local timezone is Europe/Tallinn

  When timezone is set to "Europe/Tallinn", everything is ok:
  # dpkg-reconfigure tzdata -> Europe/Tallinn
  # date
  Tue Jun  3 14:34:21 EEST 2014

  # date +%z
  +0300

  # date -u
  Tue Jun  3 11:34:59 UTC 2014

  I need to set timezone to GMT+2, to avoid dailight savings time.
  When I set timezone to "GMT+2", things fall apart. Timezone is shown GMT+2/GMT-2. Clock is set to GMT-2.
  # dpkg-reconfigure tzdata -> Etc/GMT+2

  # date
  Tue Jun  3 09:36:21 GMT+2 2014

  # date +%z
  -0200

  # date -u
  Tue Jun  3 11:37:43 UTC 2014

  When I set timezone to "GMT-2", then it's turned around. Timezone is shown GMT-2/GMT+2. Clock is set to GMT+2.
  #dpkg-reconfigure tzdata -> Etc/GMT-2

  # date
  Tue Jun  3 13:39:35 GMT-2 2014

  # date +%z
  +0200

  # date -u
  Tue Jun  3 11:39:56 UTC 2014
