cyrus-timezones package for Cyrus IMAPd

cyrus-timezones provides timezone information for the Cyrus IMAP
Server (https://github.com/cyrusimap/cyrus-imapd).

By use of the vzic timezone compiler it compiles VTIMEZONEs based on
the latest IANA timezone database (https://www.iana.org/time-zones).

The generated timezones are installed at

    ${datadir}/cyrus-timezones/zoneinfo

and their absolute path is defined as a pkg-config variable:

   $ pkg-config --variable=zoneinfo_dir cyrus-timezones
