If the time is curved, then it might be non-linear, though I dont know if that would require multiple time dimensions or not.

For me, it is nigh impossible to conceive of a curve without using at least two dimensions. If time is curved, it seems that there is a strong hint of multi-demensionality.

I agree that in our view it would probably be multidimensional, though there could always be the possibility that every other dimension is curved around it.
