I've been under GA, and yeah, first you feel cold in your vein where they start plasma infusion (without the drug yet I believe) and then you wake up in post op. No sense of time. GA is insufficient demonstration though -- it is possible that memory recording and time keeping parts are down (there are several ways brain keeps time iirc), but other parts are working. I think there is always some electrical brain activity under GA, so something is still going on, just not enough to track time.
