Description:
------------
In PHP 7.1 (7.1.18) the timezone SGT is missing in the PHP timezone database.
In version 7.0.22 it could be used.

Other timezone like gmt, utc, cet,... are fine.

Could you please add it again?

Test script:
---------------
$datetime = DateTime::createFromFormat ('H:i T' , '09:30 SGT');
var_dump(DateTime::getLastErrors());

Expected result:
----------------
no error

Actual result:
--------------
Error: 'The timezone could not be found in the database'

This is a bug in tzdb. Please refer to http://tz.iana.narkive.com/NDLAJ1xs/tz-sgt-abbreviation-is-missing-from-the-iana-tz-database for details. Updating tzdb in core should fix this.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Timezone abbreviations (except UTC) should not be used[1]; use the
proper Asia/Singapore instead.

@gooh: Based on that discussion this not a bug, but an intentional normative change that will not be reserved. Current tzdata does not reintroduce SGT.
