+ #
+ #  The program was produced on an experimental basis in the course of the

+ #  Each user of the program will agree and understand, and be deemed to

+ #  modification, copying and distribution of the program and the
+ #  production of secondary products from the program.
+ #
+ #  In the case where the program, whether in its original form or

+5. Time Zone Database
+
+  ICU uses the public domain data and code derived from Time Zone
+Database for its time zone support. The ownership of the TZ database
+is explained in BCP 175: Procedure for Maintaining the Time Zone
+Database section 7.
+
+ # 7.  Database Ownership
+ #
+ #    The TZ database itself is not an IETF Contribution or an IETF
+ #    document.  Rather it is a pre-existing and regularly updated work
+ #    that is in the public domain, and is intended to remain in the
+ #    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
+ #    not apply to the TZ Database or contributions that individuals make
+ #    to it.  Should any claims be made and substantiated against the TZ
+ #    Database, the organization that is providing the IANA
+ #    Considerations defined in this RFC, under the memorandum of
+ #    understanding with the IETF, currently ICANN, may act in accordance
+ #    with all competent court orders.  No ownership claims will be made
+ #    by ICANN or the IETF Trust on the database or the code.  Any person
+ #    making a contribution to the database or code waives all rights to
+ #    future claims in that contribution or in the TZ Database.
