                    The scheduled date and time in ISO 8601 format with a
                    numeric UTC offset (e.g. `+00:00`). **Important:** The `Z`
                    suffix is not accepted and returns a 500 — always use a
                    numeric offset like `+00:00`. The time must be at least 2
                    minutes in the future (earlier values return a 400). Bolna
                    rounds the start up to the next 10-minute mark, so a request
                    for `12:03` runs at `12:10`.
