  We find new solutions to the five-dimensional Einstein-Maxwell-dilaton theory
with cosmological constant where the dilaton field couples to the
electromagnetic field as well as to the cosmological term with two different
coupling constants. The five-dimensional spacetime is non-stationary and is a
conformally regular spacetime, everywhere. Both the dilaton field and the
electromagnetic field depends on time and two spatial directions. The
cosmological constant takes positive, negative or zero value, depending on the
value of coupling constant. We study the physical properties of the spacetime
and show that the solutions are unique in five dimensions and can't be uplifted
to higher-dimensional Einstein-Maxwell theory or Einstein gravity in presence
of cosmological constant. Moreover, we construct new solutions to the theory
where both coupling constants are equal.
