Does string theory allow for multi-dimensional time?

String Theory (or "M-Theory" as it's more or less known as now amongst the theoretical physics community) postulates that the most fundamental unit of all matter is a string that "vibrates" in higher dimensions producing everything including all matter and all forces that we see around us.

Time won't be more than one dimension because dimensions themselves cannot be divided up.

What COULD result from each passing moment however, is that with each passing "moment" (however that would be measured) is that there is a totally separate universe going off on a different tangent so to speak. This was implied by quantum physics before superstring theory was even thought about. So there is kind of a superposition of an infinite number of universes, each cancelling each other out to result in the one that you see.

Back to the original question - Time is no different than depth or width - you can add, but you cannot divide. Depth will be one measurement, width another, height another, time another, and with string theory we go "Hey look! More!" - but not more "time" or "height" or "width".

You also must realize that all of these labels (time, width, depth etc) are nothing more than labeling conventions and say nothing about the dimensions themselves. As Einstein has said - Time is nothing more than a great illusion.

Your above analogy is what I was asking. But, does anything in string-theory explicitly disallow the concept?
