I believe Logstash is inserting the current time based on [this answer](https://discuss.elastic.co/t/add-field-timestamp-with-current-time/59862). Since your timestamp field is a string upon being input into Logstash, I think you'll have to format the string and convert it into a date. [This](https://discuss.elastic.co/t/conver-string-to-date-or-replace-timestamp-solved/32957) should be of assistance.
