Time is relative to how old you are. When you are young it seems like time chugs along from day to day. When you are older time picks up speed and there isn't enough of it. When you approach death time is a path to your eternal happiness.
Time is many things. It can be physical, linear, etc. depending on what aspects you want to view it in. It moves either backwards, forward, or present following a linear motion by the Newtonian theory. We move through space but it doesn't move. According to Einstein time moves slower for a person in motion rather then a person who isn't in motion because time and space is relative, and Euclid says it's dimensional.
