  The past, present and future are not fundamental properties of Minkowski
spacetime. It has been suggested that they are properties of a class of
information gathering and utilizing systems (IGUSs).The past, present and
future are psychologically created phenomena not actually properties of
spacetime. A human is a model IGUS robot. We develop a way to establish that
the past, present, and future do not follow from the laws of physics by
constructing robots that process information differently and therefore
experience different nows (presents). We construct a customized virtual reality
(VR) system which allows an observer to switch between present and past. This
robot (human with VR system) can experience immersion in the immediate past ad
libitum. Being able to actually construct an IGUS that has the same present at
two different coordinates along the worldline lends support to the IGUS
hypothesis.
