Subject [jira] [Commented] (SPARK-16366) Time comparison failures in SparkR unit tests
Date Tue, 02 Jan 2018 06:45:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-16366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16307728#comment-16307728
] 

Felix Cheung commented on SPARK-16366:
--------------------------------------

not 100% sure, but a a similar timestamp test failure was reported at one point and I thought
both cases were caused by the machine time zone and R picking that up.
