I'm trying to parse 180711T221704.507399z into @timestamp with

date {  
match =\> ["log\_time","yyMMddHHmmss.SSSSSS"]  
}

but keep getting "dateparsefailure".

I've tried "ISO8601", adding the T, z, and a everything short of breaking it up. Appreciate suggestions.

Have you tried `yyMMddHHmmss.SSSSSS'z'` (yes, with single quotes around the "z")?

date { match => ["message", "yyMMdd'T'HHmmss.SSSSSS'z'"] }

```
