[jira] [Commented] (ARROW-617) Time type is not specified clearly

    [ https://issues.apache.org/jira/browse/ARROW-617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15905959#comment-15905959 ] 

Julien Le Dem commented on ARROW-617:
-------------------------------------

Currently the java TimeVector supports millis only on 32 bits.
the c++ Time Vector is 64bits.

> 2 options:
> - Use 64 bits for microseconds and nanoseconds, 32 bits for other units
> - Use 64 bits for everything
> The latter is simpler to implement, the former saves space.
