[Bug 1901020] Please test proposed package

[Łukasz Zemczak]

Hello Brian, or anyone else affected,

Accepted tzdata into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/tzdata/2020d-
0ubuntu0.16.04 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
xenial to verification-done-xenial. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-xenial. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  New upstream version, affecting the following future timestamps:
    - Fiji starts DST later than usual, on 2020-12-20.
    - Palestine ends DST earlier than predicted, on 2020-10-24.
    - Revised predictions for Morocco's changes starting in 2023.
    - Canada's Yukon changes to -07 on 2020-11-01, not 2020-03-08.
    - Macquarie Island has stayed in sync with Tasmania since 2011.
    - Casey, Antarctica is at +08 in winter and +11 in summer since 2018.

  Additionally, upstream removed the "old" SystemV timezones, but the
  SRU will ensure that they are kept. Subsequently, these should be
  checked for using the following:

  zdump -v SystemV/MST7
  zdump -v America/Phoenix

  The information returned by SystemV/MST7 should be included in
  America/Phoenix's output.

  Verification is done with 'zdump'. The first timezone that gets
  changed in the updated package is dumped with "zdump -v
  $region/$timezone_that_changed" (this needed to be greped for in
  /usr/share/zoneinfo/). [For example: "zdump -v Africa/Casablanca".]
  This is compared to the same output after the updated package got
  installed. If those are different the verification is considered done.
