# This is an ICU-specific file with the same format as regular
# tzdata
time zone files, for consistent parsing by the tools that

"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
# SystemV

# IANA tzdb file
'systemv' file has these SystemV/* zones commented out up to 2020a.
#
'systemv' file was removed in 2020b. We keep them in this supplemental zone data
# file for compatibility purpose.
