O que é duração do tempo?

Time duration is the amount of time that passes between two points in time, or the length of time something takes. This calculator finds duration between two clock times, adds or subtracts duration from a time, converts between time units, and computes end time from a start time and elapsed duration.

Time format: HH:MM or HH:MM:SS (24-hour)

Formato de hora

HH:MM: Horário: Minutos (por exemplo, 14h30)

HH:MM:SS: Horas: Minutos: Segundos (por exemplo, 14:30:45)

Use 24-hour format (0-23 hours).
