I have a time enabled layer that I would like to increment by three month intervals (1/4 year) using a time slider in a web map.

The initial date for my features is 3/../1998. I have changed the start date to 1/1/1998 so that the first time slider interval begins at the beginning of the year, the second interval starts on April 1st, etc...

I have selected Advanced settings -> "Playback position saved with map."

This works beautifully until I close the browser and reopen it. "Playback position saved with map" remains turned on, but the first date resorts back to 3/../1998.

Is it possible to make this thing stick?

Thank you,

Randy McGregor
