Hi,

Looking for help with a date and time filter in logstash. I created a new Time field putting together a previous date and time field that I subsequently drop.

The new Time field looks like the below in my output:  
`"Time":"2021-01-05 00:00:10"`

I have tried the following filters, but still not getting it to replace the @timestamp:

```
	date { 
		match => ["Time", "[yyyy-MM-dd HH:mm:ss]" ]
		target => "@timestamp"
	}

```

and

```
	date { 
		match => ["Time", "[YYYY-MM-dd HH:mm:ss]" ]
		target => "@timestamp"
	}

```

neither has worked. Any other suggestion would be great

There is no `[` and `]` around the time format.

You should use

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

```

You also don't need the `target` option if your target is the `@timestamp` field.
