Logstash date parsing

Question

I am having issue mapping my date to @timestamp

Here is the log format ( 0 - 12 for hr - below eg is for 8 PM )

09/04/2014 8:14:12

I am filtering it as below -

%{DATESTAMP:StatshttpDate}

I tried both below and do not seem to work. date { match => [ "StatshttpDate", "MM/dd/yyyy h:mm:ss" ] target => "@timestamp" }

     date {
             match => [ "StatshttpDate", "MM/dd/yyyy hh:mm:ss" ]
             target => "@timestamp"
         }
