+# 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.

+# Zone	NAME		GMTOFF	RULES	FORMAT
+Zone	Etc/Unknown	0	-	Unknown
