The Geological Time Class name is a compromise used to represent a Time at several scales : A mandatory and precise DateTime used to characterize a TimeStep in some TimeSeries and an optional Age Offset (corresponding to an Geological Event occurrence) in years. This Age Offset must be positive when it represents a GeologicalEvent occurrence in the past. We do not mandate this Age Offset to be only positive because we could have to realize simulation of Geological Event occurence in the future.
When the Geological Time is used to represent a Geological Event Occurrence the DateTime must be set by the writer at a date not precedent to the 01/01/1950. Any DateTime (even the creation Date Time of the instance) could be set in this Attribute field.
