This is the published start of the auction. It's what consignors see, what the sale calendar sorts by, and the anchor for your run order. It's the planned time — when the ring actually opens, Tally records that separately as the actual start, so the two can differ without you editing this.
Scheduled start is required on every sale. Times are shown in your barn's local time zone (set on the tenant, default America/Chicago).
