Hello all,

i need help setting @timestamp from fields, why date plugin is not parsing my custom fill\_date correctly?

```
mutate {
    add_field => { "fill_date" => "%{FillDate} %{FillTime}" }
}

date {
    timezone => "UCT"
    match => ["fill_date", "yyyy-MM-dd HH:mm:ss.s"]
    target => "@timestamp"
}

```

### logstash output

```
{
     "FillDate" => "2020-11-10",
     "FillTime" => "10:30:33.286000",
     "fill_date" => "2020-11-10 10:30:33.286000",
     "@timestamp" => 2020-11-22T11:56:02.736Z
}
```
