Logstash Date filter ISO8601 Issue

Hi there I am having some trouble with the date creation for my logs when they enter logstash, the end goal is to have the @timestamp field match the timestamp for the Auth or Syslog as thy are processed. These are in high precision format as exampled below. Please note the date match string is my throwing sepggiti at it as I have tired them on there own however nothing has run correctly so far, any help would be greatly received.

The following is a debug trace log from attempting to process logs, as you can see they are out about a second, I have also attempted to run old logs and they are not given the correct time stamp either.

My test config should attached as I was informed my post is too large.

date { match => [ "system.auth.timestamp", "yyyy-MM-dd'T'HH:mm:ss.SSSSSSZ" ] }

should do it.

This input deals with all the timestamps are incoming, the item you suggest was very close just needed an extra Z on that one as the timestamp has the : in between the two

match => [ "system.auth.timestamp", "yyyy-MM-dd'T'HH:mm:ss.SSSSSSZZ", "yyyy-MM-dd'T'HH:mm:ssZZ", "yyyy-MM-dd'T'HH:mm:ss.SSSZZ", "ISO8601" ]
