Spanish uses the singular to refer to one and the plural to refer more than one or zero of something. Is the same for material things and other abstract concepts, for example, time measures: hours, minutes, seconds...
Tengo 1 hora libre.
Faltan 2 horas para terminar.
Finalizará en 0 horas 5 minutos y 2 segundos.
Is it correct, in English, to say, for example?
The process required 0 hours and 5 minutes.
