--------------------------------------------

Hi [~toopt4],

I think there are two different issues here. First, the correct pattern for this string is as follows.
{code:java}
select x, to_timestamp(x,"MMM dd yyyy hh:mm:ss.SSSSSSa") from (select 'Apr 13 2021 12:00:00.001000AM' x);
{code}
The other problem is that in spark 2.4.6 this pattern (SSSSSS) with more than 5 characters apparently doesn't work. But I have tested it in 3.1.1 version and it works fine.

Regards
