Here is my sample log file:

```
20:54:50,406 TRACE [com.test.my.process.module.GARBAGE06] (Thread-15 (ActiveMQ-client-global-threads-1006309389)) [2019-06-07][20:04:12][5239354][TESTTRN][GARBAGE06][coreProcess - EXIT]

```

The date I need to parse is the 2 parts in brackets  
[2019-06-07][20:04:12]

What is the best way to get that out in a usable date format? It doesn't appear that there is a PATTERN set up that matches this.

```
    grok {
        match => { "message" => '\[(?<[@metadata][date]>%{YEAR}-%{MONTHNUM}-%{MONTHDAY})\]\[%{TIME:[@metadata][time]}' }
        add_field => { "[@metadata][ts]" => "%{[@metadata][date]} %{[@metadata][time]}" }
    }
    date { match => ["[@metadata][ts]", "YYYY-MM-dd HH:mm:ss" ] }
```
