</div>

this is my code:

if [fields][log\_module] == "apacherror" {  
grok {  
match =\> { "message" =\> "[%{DATA:timestamp}]" }}  
date {  
match =\> ["timestamp" , "EEE MMM dd HH:mm:ss YYYY"]  
locale =\> "en"  
}  
}

It seems unlikely that your grok will match just the timestamp, but in case it does, the date pattern has to match the whole of the field, so you should use `EEE MMM dd HH:mm:ss.SSSSSS YYYY`.
