[Bug 1734967] Re: tzdata info for WGT/WGST broken

[Eric Desrochers]

Nish,

Yes the Ubuntu php build is configure with tzdata as follow :

debian/rules:           --with-system-tzdata

and tzdata is a Depends: for a quit some derived binary package of php.

(The above is observation from bionic php7.1 source pkg)


# debian/php-common.README.Debian
----------------------------------------------------------------------
Timezone data from system timezone database
----------------------------------------------------------------------

  Debian PHP has been patched to use the system wide timezone database
  from the tzdata package, making sure any updates there are
  automatically used by PHP as well.

  Note that this requires that the PHP process has access to
  /etc/localtime and /usr/share/zoneinfo. For any regular installation
  this should be the case, but in specific secured environments when
  reading the timezone database is impossible PHP will give a
  "Timezone database is corrupt - this should *never* happen!" error.

  tzdata info for WGT/WGST broken

Bug description:
  Using "America/Godthab" timezone, "WGT/WGST" is no longer displayed
  from date command but instead just "-03". Problem is evident in PHP
  applications too, which now think we're in Sao Paolo.

  This appears to have changed with latest tzdata update or perhaps in
  combination with change from DST.

  Same problem on 16.04, 17.10 and Debian 9.
