Was 81 minutes ago in the same hour?
Whether 81 minutes ago falls in the same clock hour depends on the current minute. If the current minute is at least 81, then 81 minutes ago is in the same hour. Otherwise it crossed into the previous hour — which may also be the previous day if the moment sits near midnight. The live result above handles this rollover automatically.
