Special Theory of Consiousness

Incident:
Myself and my friend are standing on a ground and there is a apple tree in between us. Initially both of us are facing towards the apple tree and we see a apple standing on the tree. After some time my friend turns around and starts observing a cricket match going on in the ground while i continue to observe the apple. After some time the apple falls down to the ground.

Observation by my consciousness:
I know that the apple had moved from the top of the tree to the ground.

Observation by my friend:
He still assumes that the apple is on the top of the tree.

You will get different answers from both of us if you ask us where the apple is. Which of us is correct. You would tell that i am right as the information that my friend has is outdated. He is having a information that was true at a previous time and not now.

So time is considered to be a consistent scale according to which everything else is measured. Even our consciousness. Is this true? Can our consciousness be dependent on time.
