Problem with timestamp field

[Prabhav (Gupta)]

I want to upload a .csv file to elasticsearch but the main problem that i am facing is with the formatting of timestamp field.
I want to be able to add a field in the format of
HH.mm.ss.SSS but all i can find is formatting for the 4 types that have been given in the link below.
https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html#plugins-filters-date-options
It'd be great if someone could tell me how can i upload data to elasticsearch with logstash and havig proper time_stamp formatting.

You can use the format you want

Example

filter {
date {
match => [ "logdate", "MMM dd yyyy HH.mm.ss.SSS" ]
}
}
