Hi All,

I'm using spark 2.4 and trying to convert a timestamp column to unix with milliseconds using the unix_timestamp function. 

I tried to convert the result to double cast(unix_timestamp(timestamp) as double). 
I also tried using the timestamp format "yyyy-MM-dd HH:mm:ss.sss" and no matter what I already tested I just kept getting the unix time in seconds. 

Looking for any new ideas.
