ctl_zoneinfo

Cyrus IMAP documentation perform operations on the zoneinfo database

ctl_zoneinfo [ -C config-file ] [ -v ] -r version-string
ctl_zoneinfo [ -C config-file ] [ -v ] -w file


ctl_zoneinfo is used to perform various administrative operations on the zoneinfo database.

ctl_zoneinfo reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.

Use the specified configuration file config-file rather than the default imapd.conf(5).

Enable verbose output.

Rebuild the zoneinfo database based on the directory structure of configdirectory/zoneinfo. The database to be rebuilt will be in the default location of configdirectory/zoneinfo.db unless otherwise specified by the zoneinfo_db_path option in imapd.conf(5). The version-string should describe the source of the timezone data (e.g. "Olson:2020a") and will be used by the tzdist module of httpd(8). The version-string must contain a colon between the description and the version.

Reads Windows Zone XML file.
