# date (after installation)
Tue Apr 2 03:50:19 -03 2019
All time zones have not yet been converted, our development team is still working on the conversions.
 
Please refer to the IANA doc with the new standards:
https://mm.icann.org/pipermail/tz-announce/2017-February/000045.html
 
The document says:
...

    part of the ongoing project of removing invented abbreviations.
    This avoids the need to invent an abbreviation for the new Chilean
    new zone. Similarly, switch from invented to numeric time zone
    abbreviations for ... Singapore, ...
 
zdump warnings are expected as all the timezones have yet to be updated. The new code when ported from IANA will no longer report the warnings.
