+function t = dynTimeIndex() % --*-- Unitary tests --*--

+% t = dynTimeIndex()
+%
+% Constructor for the dynTimeIndex class.
+%
+% INPUTS:
+%  None.
+%
+% OUTPUTS:
+%  * t, dynTimeIndex object.
+%
+% DESCRIPTION:
+%  The dynTimeIndex object is used to shift backward or forward dynSeries objects. For instance, if ts
+%  is a dynSeries object and t is a dynTimeIndex object then the following expressions are equivalent:
+%
+%      us = ts.lag()
+%      us = ts.lag(1)
+%      us = lag(ts,1)
+%      us = ts(t-1)
+%
+%  This class has only one member: t = int8(0) when instantiated.
