I got the following rule:
	(INT 'h')? (INT 'min')? (INT 's')? (INT 'ms')? (INT 'us')?

so the time units will get highlighted and thats correct.
But in the language it also should be possible to set these as an identifier like:
var int ms;
var int h;

The ID rule for variables is:
terminal ID_VAR:
	( ('a'..'z') ('a'..'z' | 'A'..'Z' | '0'..'9' | '_' )*) | '_'

So in the moment there will occur an error.
Is there a way to make this possible?

Thanks in advance.

you have to introduce a datatype rule and use it instead of ID

MyID: ID | "keyword1" .... | "keywordn";
