@cperez86,

This isn't really the best place for such a question as this forum is about non-English / Multi-lingual queries,

You might have better luck in the main "Developer" forum. My guess though, is that if that's referring to a "Duration" field or a value from a "task timed worked" entry would be no it has to be a duration rather than a date because they are two different data types,

Many thanks,
kind regards
