I usually use this 2 syntax to get the lists of tasks:

option 1
from clearml import Task custom_task_filter = {...} tasks_list = Task.get_tasks( task_filter=, task_name=name_custom_tasks )
option 2
from clearml.backend_api.session.client import APIClient client = APIClient() tasks_list_via_api = client.tasks.get_all( ...)
In both case if I get the element from the list, I am not able to get when the task started. Where is info stored?
