| ================= |
| |
| 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. |
