1. A pump assembly comprising: a centrifugal pump driven by an electric motor having a time control with a time display comprising:a plurality of illumination devices to each of which a time is assigned;wherein the time display continuously represents present time of day and a settable switching time,wherein the plurality of illumination devices are light emitting diodes and form a first circularly annular row of light emitting diodes having a first color and displaying one of the present time of day and the settable switching time and a second circularly annular row of light emitting diodes concentric to and within the first circularly annular row of light emitting diodes, the second circularly annular row of light emitting diodes having a second color different the first color and displaying the other of the present time of day and the settable switching time, andwherein the illumination devices of the first circularly annular row of light emitting diodes and the illumination devices of the second circularly annular row of light emitting diodes lie in a paired manner on a radial line. 2. The pump assembly according to claim 1, wherein the time control has a superordinate time control mode having a switch-on time and a subordinate time control mode which switches off the motor of the pump in settable intervals when the time control is in the superordinate time control mode. 3. The pump assembly according to claim 1, wherein an operating element is provided for setting both the present of day and the settable switching time, wherein the present time of day is to be set before the settable switching time. 4. The pump assembly according to claim 1, wherein markings for the present time of day are provided, which are arranged around the illumination devices of the first circularly annular row of light emitting diodes in an annular manner. 5. The pump assembly according to claim 1, wherein the first circularly annular row of light emitting diodes and the second circularly annular row of light emitting diodes represents the present time of day and the settable switching time with 24 hours or 12 hours and corresponds to an analog clock. 6. The pump assembly according to claim 1, wherein the pump assembly at least in a region of the electric motor comprises a housing which is round in cross section and which ends in a plane end-wall which is away from the centrifugal pump, and the time display is arranged on the plane end-wall. 7. The pump assembly according to claim 6, wherein the time control comprises operating elements which are arranged on the plane end-wall. 8. The pump assembly according to claim 1, wherein an end-wall is part of a control and connection housing which connects to a motor housing in an axial direction and houses a circuit board on which the plurality of illumination devices and operating elements are arranged, and that recesses for the plurality of illumination devices or fibre-optics connected thereto and for the operating elements on the circuit board are provided in the end-wall. 9. The pump assembly according to claim 8, wherein the end-wall is closed to the outside of the pump assembly by a film provided with markings. 10. The pump assembly according to claim 8, wherein the operating elements are formed by micro-buttons. 11. The pump assembly according to claim 8, wherein the operating elements are arranged within the first circularly annular row of light emitting diodes and the second circularly annular row of light emitting diodes. 12. A pump assembly according to claim 8, wherein the operating elements are formed by, a button for menu selection, a button for confirmation and a button for time setting, respectively. 13. A pump assembly according to claim 12, wherein at least three operating conditions may be set in the menu selection, specifically: permanent operation, time-controlled operation and setting operation, wherein an individual operating condition illumination device of a plurality of operating condition illumination device is assigned to each operating condition.
