Hi,

I want to convert a date which is like this :  
2020-09-18 15:42:41.5721

To do so, I have tried to use date plugin but it seems that it doesn't work. I have this \_dateparsefailure and my @timestamp hasn't changed

```auto
    date {
		match => ["time_stamp", "yyyy-MM-dd HH:mm:ss.SSS"]
	}

```

I've also tried to match with "ISO8601" as I read time\_stamp like this :  
%{TIMESTAMP\_ISO8601:time\_stamp}.  
Of course I've checked and it contains 2020-09-18 15:42:41.5721.

Can anyone help me ?

Thanks

I found a solution :  
I deleted the date filter and y added this to my mutate filter :

```
        gsub => [
                  "timestmp", " ", "T"
                ]

```

It's automatically converted as date type then

The reason that does not work is because you have 4 digits sub-second. It would work if you used

```
match => ["time_stamp", "yyyy-MM-dd HH:mm:ss.SSSS"]

```
