Help setting DB Connect input timestamp using yyyy-MM-dd HH:mm:ss.SSS format

[johnward4]

I'm trying to work with a data input using DB Connect version 3.0 and I cannot get the below input to save using the field alias 'time' that using this format :

2020-03-21 00:11:12.387

Based off this article I added these configurations to my stanza to help DB Connect identify the correct timestamp format :

input_timestamp_format = yyyy-MM-dd HH:mm:ss.SSS
output_timestamp_format = yyyy-MM-dd HH:mm:ss.SSS

*The LogEntryId is my rising column and returns as column #1
*The time column/Timestamp returns as column #2

I've also uses the below Answers suggestion to try to resolve the NULL values possible issue :
