hola a todos, 
Necesito ayuda para convertir mi formato de hora. Dentro del conjunto de datos que tengo, mi hora está en formato de xx H xx MIN xx SEG,  por ejemplo 0 H 47 MIN 48 SEG. Estoy intentando convertir estos tiempos en formato de un numero especifico de minutos o segundos, donde las 0 H 47 MIN 48 SEG convertirían en 47.8 minutos o 2,868 segundos

    Hi @ISA_MOSQUERA

    If you want to convert dates, have a look at the operator "Nominal to Date" in combination with "Date to Numerical". For more difficult use cases, the operator "Generate Attributes" has extended date functionality.
