# 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.
