[jira] [Commented] (SPARK-30668) to_timestamp failed to parse
2020-01-27T20:06:11.847-0800 using pattern "yyyy-MM-dd'T'HH:mm:ss.SSSz"
[ https://issues.apache.org/jira/browse/SPARK-30668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17028515#comment-17028515 ]
Maxim Gekk commented on SPARK-30668:
------------------------------------
[~dongjoon] Output of your example is surprised - it doesn't contain the fractional part of seconds. 847 is printed on the master if we change the pattern z -> Z.
