| # This is an ICU-specific file with the same format as regular | |
| # tzdata time zone files, for consistent parsing by the tools that | |
| # turn "Olson" tzdata into ICU's zoneinfo.txt. | |
| # The purpose of this file is to give ICU a superset of the time zones | |
| # that are in CLDR and also include legacy ICU time zones originally | |
| # in tz.alias for rataining backward compatibility. | |
| # Add Etc/Unknown, defined by CLDR. Give it Etc/GMT behavior. | |
