=================
|
|
|
|
download-iana-data.py
|
|
- A helper script run before update-tzdata.py.
|
|
It downloads the latest tzdata update from IANA and puts it in
|
|
the system/timezone/input_data/iana directory for use by the
|
|
update-tzdata.py script.
|
|
|
|
There are sometimes code and metadata changes associated
|
|
with tzdata updates that should be applied to ICU at the same time.
|
|
e.g. see http://bugs.icu-project.org/trac/search?q=2015d
|
|
|
|
update-tzdata.py
|
|
- Regenerates the external/icu and system/timezone/output_data timezone
|
|
data files.
|
|
|
|
CTS tests for ICU, bionic and libcore should be run before and after.
