Hi Anton, The TDate looks quite "verbose". I thought that all that was missing in root was a way to put date strings on a linear scale so that arithmetic could be done or graph axes build. The Julian scale is an easy way to accomplish this. Complicated issues concerning daylights-saving time etc. can be investigated with c functions like time(5) and date.
