Help on date filter plugin to parse 5/24/2016 6:10:20 AM

I tried to use date plugin to parase date as 5/24/2016 6:10:20 AM and 5/24/2016 1:00:15 AM.
My configuration is as below. but it doesn't work. Could anyone help me?

date {
match => [ "ACS_Timestamp", "M d YYYY H:mm:ss a","ISO8601"]
target =>"@timestamp"

It's literal, so you need to include things like the /.

Have you solved your problems ? i have the same problome
