I guess it has a circular form, but in each cycle events are "re-written" (time is "recycled"), they're different but part of cycles. It's not a circular form as in events being "repeated". In practice it's similar to spiral time.

It can be all three depending on how one would like to express it. Time is motion using numerical expression.

It could be a circle, but it's probably more like a Calabi-Yau manifold mixed up with other sub-Plank length dimensions.

I'm not certain, but I figure that, if it were a larger dimension, we'd be able to move around in it.

I'm thinking the spirals end up in a circle when all is said and done...

[errorist]

... and this circle is so small that becomes singularity. Everybody agrees with you. There is nothing to do more.

Since time is infinite then I say it's circular. If the universe expands and then contracts and then expands over and over again, this too represents in my mind, a circular pattern over the course of time.

Where we going with this?

Time for us in daily living and in fact during our miniscule existence would appear linear. Because we cannot appreciate the true scale of time, it may be hard to wrap our head around it being a circular entity.

I guess we will be doing this again a quadrillion years from now then .........
