I agree that their perception of time will be different. The first thing to realize is that time, in this respect is relative to how fast an individual lives. In fact this happens to humans over their life time. When we are young it seems as though a year is a long time. When you get older the length of a year appears much shorter. And of course our perception of time depends on many other things. If you are doing something that you are very interested in time may pass very quickly for you. You will wind up saying 'Is the day already over?' But other times it will seem as though the day will never end. So time perception is very erratic.
In general small things live a much shorter life than larger things. An individuals perception of time rate depends, in part, on how fast things change in its life. So a small creature that has a short life would have a perceived time rate that is much faster than a large creature with a long life.
