Thank you for the ideas below.? That did work.? I thought I had tried "10 mins" before, but maybe I used just 10 min. ============== Yes, you can have date_breaks = "n mins" where n is any integer. date_breaks = "15 mins" date_breaks = "30 mins" date_breaks = "1 hour"?? # or "1 hours", plural The only way I know is to try different values until you find one suitable.
