Time-Specific Markets settle based only on what happens within a chosen window of the match — for example, "Result (1X2) Per Minute Range 15:00–29:59".
Example: a bet on the home team for the 15:00–29:59 range only considers what happens in that 15-minute window, starting from a 0-0 score, regardless of anything that happened before or after it.
