  Starting from the non-BPS D$(p+1)$-brane action we derive an effective action
in $(p+1)$ space dimensions by studying the fluctuations of various bosonic
fields around the time-like tachyonic kink solution (obtained by Wick rotation
of the space-like tachyonic kink solution) of the non-BPS brane. In real time
this describes the dynamics of a space-like or Euclidean brane in
$(p+1)$-dimensions containing a Dirac-Born-Infeld part and a Wess-Zumino part.
The WZ part is purely imaginary and so the action is complex if it represents
the source of the time-dependent background of type II string theory i.e. the
S-brane. On the other hand, the WZ part as well as the action is real if it
represents the source in type II$^\ast$ string theory i.e. the E-brane. The DBI
part is the same as obtained before using different method. This is then
further illustrated by considering brane probe in space-like brane background.
