Why does this date filter get a \_dateparsefailure?

```
input { generator { message => 'N' count => 1 } }
output { stdout { codec => rubydebug } }
filter {
  mutate { add_field => { "DateReported" => "1292015 1745" } }
  date { match => ["DateReported", "Mddyyyy HHmm"] }
}

```

I am getting to the point where I am considering a ruby filter to rjust it.

No. I'm wondering if M is consuming the 12, leaving dd to not match 9.
