TimeSpan is a highly used Data Type when working with time objects. A TimeSpan object represents a time interval (duration of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second.
It is used frequently in API's that deal with time (Like the Azure Maps API's for instance) and having to deal with this manually (via an optional Extension module) is really cumbersome and time intensive. Please consider to add support for this Date Type.
