Ummm... no, I think more accurately, hysteresis is when an event, such as

switch closure, takes place at one point during an increasing stimulus,

but at another place during a decreasing stimulus.  Some examples of

devices exhibiting hysteresis are thermostats, schmitt triggers, and

certain inductive devices.  Examples of devices exhibiting time delays

are one-shot multivibrators, time-delay relays, and integration circuits.
