Bug description:
  Mongolia stopped following DST this year. The timezone information in
  Ubuntu 16.04.2 LTS is outdated:

  $ TZ=Asia/Ulaanbaatar date --date="2017-05-16 12:15 UTC" +%H:%M
  21:15

  The correct output is '20:15'.

  This has been updated in version 2017a of tzdata. My Ubuntu 16.04 is
  using 2016j. I guess the previous LTS versions are also affected.
