6.10. Configuring the Overcloud Time Zone
You can set the time zone of your Overcloud deployment using the
TimeZone parameter in an environment file. If you leave the TimeZone parameter blank, the Overcloud will default to UTC time.
Director recognizes the standard timezone names defined in the timezone database /usr/share/zoneinfo/. For example, if you wanted to set your time zone to
Japan, you would examine the contents of /usr/share/zoneinfo to locate a suitable entry:
$ ls /usr/share/zoneinfo/ Africa Asia Canada Cuba EST GB GMT-0 HST iso3166.tab Kwajalein MST NZ-CHAT posix right Turkey UTC Zulu America Atlantic CET EET EST5EDT GB-Eire GMT+0 Iceland Israel Libya MST7MDT Pacific posixrules ROC UCT WET Antarctica Australia Chile Egypt Etc GMT Greenwich Indian Jamaica MET Navajo Poland PRC ROK Universal W-SU Arctic Brazil CST6CDT Eire Europe GMT0 Hongkong Iran Japan Mexico NZ Portugal PST8PDT Singapore US zone.tab
The output listed above includes time zone files, and directories containing additional time zone files. For example,
Japan is an individual time zone file in this result, but Africa is a directory containing additional time zone files:
$ ls /usr/share/zoneinfo/Africa/ Abidjan Algiers Bamako Bissau Bujumbura Ceuta Dar_es_Salaam El_Aaiun Harare Kampala Kinshasa Lome Lusaka Maseru Monrovia Niamey Porto-Novo Tripoli Accra Asmara Bangui Blantyre Cairo Conakry Djibouti Freetown Johannesburg Khartoum Lagos Luanda Malabo Mbabane Nairobi Nouakchott Sao_Tome Tunis Addis_Ababa Asmera Banjul Brazzaville Casablanca Dakar Douala Gaborone Juba Kigali Libreville Lubumbashi Maputo Mogadishu Ndjamena Ouagadougou Timbuktu Windhoek
Once you have determined the time zone to use, you can enter its name into an environment file processing. For example, add the entry in a file named 'timezone.yaml' to set your timezone to
Japan:
parameter_defaults: TimeZone: 'Japan'
Next, use the overcloud deploy process to run the template and apply the setting:
$ openstack overcloud deploy --templates -e timezone.yaml
