Some AutoTools actions (such as JSON Read) allow the user to specify the variable(s) to be returned. I'd like to see this option available anywhere AutoTools is returning a value. I'm specifically thinking of Time, but it'd be helpful anywhere.
Without being able to specify the return value, multiple calls to AutoTools Time require two extra actions between calls: one to store %atcalculateddate in another variable so it doesn't get overwritten, and another to clear %atcalculateddate so the old value doesn't get retained when the next call doesn't return a new value. Being able to specify the return variable allows the two calls to use different names and avoid the extra steps.
