[A-z]

You probably want to use [A-Za-z] rather than [A-z], since the upper and lower case letters are not contiguous blocks.

Also

match => [ "ystem_timestamp", "EEE, dd MMM yyyy hh:mm:ss z"]

That should be system_timestamp, not ystem_timestamp.

Yeah this is a copy paste error. My original (not working config ;)) has a system_timestamp.
Plus i corrected regexp and still have a dateparsefailure :(.
