Logical Model: US Realm Date and Time - Interval

The US Realm Clinical Document Date and Time datatype flavor records date and time information. If time is provided, it must include a time zone offset.

This data type uses the same rules as US Realm Date and Time (Point in Time), but is used with elements having a datatype of IVL_TS.

Usage:

• Use this Logical Model: Note Activity, Procedure Activity Procedure and US Realm Header
