Adds a task time to a task

Some tasks, such as activities within a work breakdown structure or overall maintenance tasks will have time related information. This includes start dates, durations, end dates, and possible recurring times (especially for maintenance tasks).

Parameters:

• task (ifcopenshell.entity_instance) – The task to add time data to.

• is_recurring (bool) – Whether or not the time should recur.

Returns:

The newly created IfcTaskTime.

Return type:

ifcopenshell.entity_instance

Example:

# Let's imagine we are creating a construction schedule.
schedule = ifcopenshell.api.sequence.add_work_schedule(model, name="Construction Schedule A")

# Create a portion of a work breakdown structure.
construction = ifcopenshell.api.sequence.add_task(model,
    work_schedule=schedule, name="Construction", identification="C")
superstructure = ifcopenshell.api.sequence.add_task(model,
    parent_task=construction, name="Superstructure", identification="C3")
task = ifcopenshell.api.sequence.add_task(model,
    parent_task=superstructure, name="Ground Floor FRP", identification="C3.1")

# Add time data. Note that time data is blank by default.
time = ifcopenshell.api.sequence.add_task_time(model, task=task)

# Let's say our task starts on the first of January when everybody
# is still drunk from the new years celebration, and lasts for 2
# days. Note we don't need to specify the end date, as that is
# derived from the start plus the duration. In this simple example,
# no calendar has been specified, so we are working 24/7. Yikes!
