Every time is turned into seconds (hours × 3,600 + minutes × 60 + seconds), added or taken away, then split back into hours, minutes and seconds. Decimal hours are total minutes ÷ 60, so 1:30 is 1.5 hours. Decimals are allowed in any box, and the total is rounded to the nearest second. Blank boxes count as zero. Everything is worked out on your device.
