+%! @sp 1
+%! Let @var{sp} be an object instantiated by @ref{dynTime}, both following syntaxes can be used to update the time member:
+%! @sp 1
+%! @example
+%! sp = setTime(sp,2,[1950,4]);
+%! @end example
+%! or
+%! @example
+%! sp = sp.setFreq(2,[1950,4]);
+%! @end example
+%! @sp 1
+%! Note that the second syntax is probably slower than the first one, and should not be used in a large loop.
