When I run logstash with
```
input { generator { count => 1 lines => ['2022-04-12T05:11:47'] } }
filter { date { match => ["message", "ISO8601"] } }
output { stdout { codec => rubydebug { metadata => false } } }
```
I get
```
"@timestamp" => 2022-04-12T09:11:47Z
```
So it is parsed correctly. Note that if there is _anything_ else in your [time] field (including whitespace) it has to be in the pattern for the date filter. You cannot match against a sub-string of a field.
