AMAZON.Duration - Amazon Lex


Converts words that indicate durations into a numeric duration.

The duration is resolved to a format based on the ISO-8601 duration format, PnYnMnWnDTnHnMnS. The P indicates that this is a duration, the n is a numeric value, and the capital letter following the n is the specific date or time element. For example, P3D means 3 days. A T is used to indicate that the remaining values represent time elements rather than date elements.
