Schedule a script with arguments using 'at'

I have a bash script and I want to run it at a given time. Usually I would write something like this to run it immediately: ./my_script.sh 1 1 n 8 3 keywords here I am trying to execute the same command using the "at " command but it doesn't work. If I run this, for example: at 2230 -f my_script.sh 1 1 n 8 3 keywords here I get this error: syntax error. Last token seen: 1 Garbled time How can I run the script with arguments at a given time?
