Hello,
I would very much like to add this functionality to my application that uses timeslider. I completely understand what you write, but I have only very limited javascript skills. Would you mind sharing with me how I can have my javascript code make this call the [...]/MapServer?returnUpdates=true&f=json html and how I can then pick the two values and assign them to two variables (startTime, endTime). I would very much appreciate your help. Thanks!
