[Bug 1325949] Re: timezone selections in ETC are confusing / inverted

 

I have no intention of inventing a time machine and "fixing" POSIX.
Please don't use the Etc/* timezones if the inverted offsets confuse
you, there are many other ways to get at the timezones in human-friendly
and less mind-bending ways.

** Changed in: tzdata (Ubuntu)
   Importance: Medium => Wishlist

** Summary changed:

- timezone selections in ETC are confusing / inverted
+ Add note to Debconf template about unintuitive inverted Etc/GMT offsets

Title:
  Add note to Debconf template about unintuitive inverted Etc/GMT
  offsets

Status in tzdata package in Ubuntu:
  Confirmed
Status in tzdata package in Debian:

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
