My logstash output @timestamp is showing current date in UTC zone. While my logs are of old date and logs pattern date is 07/Aug/2019:11:23:33.024.Why both are not coming same.While i have used date filter
date {
match => [ "haproxy_timestamp","dd/MMM/YYYY:HH:mm:ss.SSS"]
locale => "en-US"
target => "@timestamp"
}
