The description of TIMELINE_MOMENT needs to be improved to describe the semantics when timeline_offset or fixed_time is null, and also to state that they cannot both be null. Additionally, an ability to specify the time origin should be added, to allow for the origin to be Work Plan, Task Plan, or repeating section.
The class CALENDAR_TIME should also be removed as a subtype of TIME_SPECIFIER, since the latter class is limited to specifying time in the day.
The description of TIMER_EVENT should also be improved to state that the duration is relative to the time of execution reaching the Task to which the event is attached.
Found a bug, removed acceptance.
Text mentions twice an attribute “offset_origin”, but it’s actually named “timeline_origin”.
Thanks, that’s now fixed and pushed.
