[~ngangam] I implemented your requests.  Code is also available for review on Github.

I did not however change the DEBUG logging.  It is expected that there are going to be cases where the timestamp fails to parse.  For example, a dirty data set may have different timestamp formats in the data.  Such a data set would generate a lot of INFO logging here as the parser would try multiple different formats until it got it right.

> Hive uses Joda time for its TimeStampParser.

> Joda-Time is the de facto standard date and time library for Java prior to Java SE 8. Users are now asked to migrate to java.time (JSR-310).
