[tz] No more DST in Brazil

PHP releases the tzdata via the "timezonedb" package in PECL:

The current version 2019.3 corresponds with the IANA TZDB 2019c.  The prior version 2019.2 corresponds with 2019b where the Brazil change was made.  Thus, you need timezonedb 2019.2 or later installed to see the Brazil change.

Additionally, every release of PHP itself includes the most currently available timezonedb package at the time of release.  Thus, you can simply update your PHP installation to the current version.

>From PHP, you can call the function timezone_version_get() to see the currently installed version of timezonedb.

You have downloaded the wrong artefacts - You have downloaded the source code for the userspace components, not the tzdata per se.

For what is worth, the new Brazil DST has been shipped as few months ago, in the 2019b release - see announcement in https://mm.icann.org/pipermail/tz-announce/2019-July/000056.html

Download tzdata (not tzcode) 2019b or 2019c and you will be good.

Dear Sirs,

I am a PHP programmer and I verified a problem when I setted a timezone location to "America/Sao_Paulo" for a program.

I observed that data was showing dates and times with 1 hour difference. After some search, I downloaded the TZ database from https://www.iana.org/time-zones/repository/tzcode-latest.tar.gz where I believe that Brazilian DST remains setted, despite of Brazilian Governament has officialy cancelled DST in Brazil as described in the file southamerica finded in the TZ database in lines 946 to 949.

I hope I could help.
