> Context:
> * DAG run triggered manually
> * Using the web application to change the state of a task
> When trying to set the state of a task, an exception is thrown: *ValueError: unconverted data remains: ..372649* (look at the attached screenshot).
> I think the problem comes from the "execution date" created by manually triggered DAGs, since the date-time includes a fractional part. In my database, I see scheduled DAGs with execution dates like "10-18T15:00:00", while manually triggered ones with dates like "09-21T16:36:16.170988". If we look at the method *set_task_instance_state* in *airflow.www.views*, we see that the format string used with *strptime* doesn't consider any fractional part.
