Depends on what you are talking about.  No Physicist would argue that
time is a fourth spatial dimension, which is what dimensions typically
refer to.

Time can be referred to as a dimension when you're talking about an
object's position space and time.  You can put whatever unit you want on
the axis of a graph and it becomes a "dimension."

But time is definitely not a spatial dimension.  For example, in the
theories that the universe is 10 or 11-dimensional, time is not one of
those dimensions.  In fact no one really knows what "time" is.  Some
theories have postulated that time doesn't really exist, but is merely
an observation of movement.  IE it's the observation of entropy that we
perceive as "time."  Fascinating stuff, actually.
