This class represents an amount of time, such as 10 minutes, 3.2 seconds, etc. This class is structurally identical to a Quantity, although the units of measure are by definition time units (e.g., hours), rather than physical units (e.g., kilograms).
In FHIR, this data type is called Duration.

• The MonetaryAmount and TimeQuantity are the same as Quantity, but they "re-define" the unit property to be bound to a particular set of valid units. For example:
  Quantity may have inches, kilograms, millilters, etc.
  TimeQuantity would have minutes, seconds, days, etc.
  MonetaryAmount would have dollars, euros, rupees, etc.
• In FHIR, TimeQuantity is called Duration
• A length of time specified as a Physical Quantity, e.g., 5 minutes, 2.5 hours.
