        zz = DateTime.new(event_time[0,4].to_i,event_time[4,2].to_i,event_time[6,2].to_i,event_time[8,2].to_i,event_time[10,2].to_i,event_time[12,2].to_i)
        event.set("@timestamp",zz)

If you want to event.set [@timestamp] then feed it a Time object, not a DateTime object. Here, for example. I believe the constructor will do the work for you in that case.
