Replace @timestamp with Time field in my log

Elastic Stack Logstash

Hi Magnus,

Here is the input in my csv file:

Message Thread Time Topic Level Interaction ID

InteractionStartEvent 4580 7/25/2017 2:39:51 AM -- -- --

Time is in 7/25/2017 2:39:51 AM

This is how am writing my config file-
input {
file{
path=>"C:\logs\testing3.csv"
start_position=>"beginning"
}
}
filter{
csv{
separator=>","
columns=>["Message","Thread","Time","Topic","Level","Interaction ID"]
}
date {
match =>["Time","YYYY-MMM-dd:HH:mm:ss Z"]
target=>"@timestamp"
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index=>"itest4"
document_type=>"itest4_log"

}
stdout{ codec => rubydebug}
}
