[jira] [Commented] (OOZIE-2867) Timezone handling for Coordinators: emphasize "Continent/City" format

["Artem Ervits (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-2867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15996011#comment-15996011 ] 

Artem Ervits commented on OOZIE-2867:
-------------------------------------

[~andras.piros] & [~rkanter] I think confusion stems from the fact that oozie info -timezones actually suggets to use the short name. Should I also change the output of oozie info -timezones command to emphasize the Continent/City format?

<code>
$ oozie info -timezones
The format is "SHORT_NAME (ID)"
Give the ID to the -timezone argument
GMT offsets can also be used (e.g. GMT-07:00, GMT-0700, GMT+05:30, GMT+0530)
Available Time Zones:
      GMT (Africa/Abidjan)
      GMT (Africa/Accra)
      EAT (Africa/Addis_Ababa)
      CET (Africa/Algiers)
</code>

> It seems that some time zone abbreviations like {{BST}} for British Summer Time silently just do not get accepted correctly by Oozie and the underlying JVM.
> It would be great to:
> * emphasize in the Coordinator Functional Specification that it's best to only use time zone format {{Continent/City}}, like {{Europe/London}}, or {{America/Los_Angeles}}, instead of other formats like {{PDT}}, {{PST}}, or {{BST}}
> * if the timezone is not recognized by Oozie, it's best to emit a {{WARN}} log and suppose {{UTC}} instead of silently ignoring the unknown specified timezone
