SDT survey: Calculate the duration between two dates (a getDiff function)

[FabiennePG]

The SDT survey needs to calculate the number of nights of a given trip, knowing the departure date and the arrival date. A getDiff function working with two dates or a difference of dates as parameters (see xpath days-from-duration) and if possible a format (days, months, years) would be welcome.

As of today (7th of january 2022), this is still a pending need for the SDT survey.

A new operator datediff is planned for next VTL release. Stay tuned!
