Yin Huai commented on SPARK-10681:
----------------------------------
[~srowen] Yeah, originally that's also my thought. However, for our SQL
timestamp values, the unit is microsecond. {{getTime}} only give us
milliseconds and once we do {{* 1000}}, we lose the precision specified in the
String. For example, we have something like {{2015-01-01 23:00:00.123456}}.
Once we use {{getTime * 1000}}, we will get {{2015-01-01 23:00:00.123}}.

> Right now, {{DateTimeUtils.stringToTime}} returns a java.util.Date whose
> getTime returns milliseconds. It will be great if we have a method to parse
> string directly to SQL's timestamp value (microseconds).
