Class DV

Represents an absolute point in time from an origin usually interpreted as
meaning the start of the current day, specified to the second. Semantics
defined by ISO 8601.
Used for recording real world times, rather than scientifically measured fine
amounts of time. The partial form is used for approximate times of events and
substance administrations.
