=== Base Template !TimeRepresentation ===

[[br]]This is a template for stating the coordinates of points in time. 
[[br]]
[[br]]!PointInTime(a, b, c, d, e, f, g) means that a is a representation of a point in time, b, c, d, e, and f are integer numbers, and g a real number, and that the coordinates of a are given by b representing the year, c the month, d the day, e the hour, f the minute, and g the second of a.

NOTE This template provides a pattern for defining points in time. While the entity type !RepresentationOfGregorianDateAndUtcTime has all attributes except hasYear optional, none are optional in the template.
