Subject [jira] Commented: (JCR-2619) improved internal representation of DATE values
Date Tue, 27 Apr 2010 12:13:32 GMT

    [ https://issues.apache.org/jira/browse/JCR-2619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12861380#action_12861380
] 

Alexander Klimetschek commented on JCR-2619:
--------------------------------------------

It should support all values that a Calendar object can have, including any timezone offset.
The maximum that I know is +14, so having the timezone running from -15h to +15h, which would
be -900 to +900 minutes, should cover every case.

> DATE values are currently internally represented as java.util.Calendar objects.
> Calendar objects have a huge memory footprint (approx 200bytes per instance) 
> and are mutable.
> i suggest to replace the internal DATE representation with a ISO8601 format string
> (immutable and approx. 85-90% smaller footprint).
