   > ok, from what I understand what is failing is to download the following 
due to a certificate issue: 
https://data.iana.org/time-zones/tzdata-latest.tar.gz which if I understand 
correctly could be done via the tzdata lib proposed. We can still download the 
other file from: 
https://raw.githubusercontent.com/unicode-org/cldr/master/common/supplemental/windowsZones.xml
   
   I don't think that's right. I think:
   
   1. ORC needs access to a distribution of the timezone database which is in 
their binary format. This is the file tree usually at /usr/share/zoneinfo on 
Linux machines. This is not the file that's hosted by IANA. I'm fixing this now 
so the ORC tests run.
   2. Arrow, including Arrow R and PyArrow, needs access to a text-based 
timezone archive. This _is_ the file hosted by IANA. We need to resolve this 
still.
   
   I'm working on improvements for (1) and need to think up a creative solution 
for (2).
