you meant, didn't you?
 
x = "time"
y = 'TEST'

You can use the #{ruby code} notation that evaluates the ruby code and inserts
the value like in double quoted strings.
In your case that would be something like:

 acl.gsub(/#{x}/,y)

Though the content of x should not be interpreted, you should write:

 acl.gsub(/#{Regexp.escape(x)}/,y)
