Description

When I try to import an exported note, the import dialog remains with no output.

I found an exception log like this.

It seems date format is the cause.

Dates in exported json from release version are like "Apr 19, 2016 12:04:58 PM",
but dates in exported json from snapshot version are like "2016-06-15T14:39:04+0000".

I found a similar issue ( https://issues.apache.org/jira/browse/ZEPPELIN-905 ) and PR ( https://github.com/apache/zeppelin/pull/933 ),
but it seems its focus is different.

I think this problem is created by this commit - https://github.com/apache/zeppelin/commit/b18811fd3694b9ca0f34b9d8c6c6697430e02c8e -
