`timestamp` argument type

G’day:
I just saw a function like this in our codebase:

function f(timestamp x){
    writeDump(arguments)
}

I asked the dev “WTH is a timestamp?” in the context of CFML, as it’s not a documented inbuilt type (<cfargument> :: Lucee Documentation). Non-inbuilt types should be treated as CFC types, and we were passing a date/time value to this function… and it was “working”.

A portable repro is here: TryCF.com

Is this just an alias for date? I also note that datetime seems to also “work”.

Def think these unorthodoxies should be documented and also noted that they diverge from CF’s behaviour.

it’s an alias, the list of supported types is here

          				break;
          			case 'q':
          				if (type.equals("query")) return TYPE_QUERY;
          				if (type.equals("querycolumn")) return TYPE_QUERY_COLUMN;
          				break;
          			case 's':
          				if (type.equals("string")) return TYPE_STRING;
          				else if (type.equals("struct")) return TYPE_STRUCT;
          				break;
          			case 't':
          				if (type.equals("timespan")) return TYPE_TIMESPAN;
          				if (type.equals("time")) return TYPE_DATETIME;
          				if (type.equals("timestamp")) return TYPE_DATETIME;
          				if (type.equals("timezone")) return TYPE_TIMEZONE;
          				break;
          			case 'u':
          				if (type.equals("uuid")) return TYPE_UUID;
          				break;
          			case 'v':
          				if (type.equals("variablename")) return TYPE_VARIABLE_NAME;
          				if (type.equals("variable_name")) return TYPE_VARIABLE_NAME;

I’ve added the missing types and supported aliases to docs
