Is there a way to format a String in Flex

Is it possible to do something like this:

var s:String = format("%20d %-10s %s", time, type, message);

In languages like C, C++, C#, Python, and Perl there is something similar to my example, but I can't seem to find it for Flex.

I don't want to create special class Formatter for every string that I want to format.
