A common problem in astronomy is the determination of the time shift between two otherwise identical time series of measured flux from a variable source, in short the determination of a time delay. One example of where this problem occurs is in the determination of the Hubble constant from multiple images of gravitationally lensed variable quasars. It is shown here that this problem is very simila...
