put https://app.asana.com/api/1.0/time_tracking_entries/
A specific, existing time tracking entry can be updated by making a PUT request on
the URL for that time tracking entry. Only the fields provided in the data block
will be updated; any unspecified fields will remain unchanged.
When using this method, it is best to specify only those fields you wish
to change, or else you may overwrite changes made by another user since
you last retrieved the task.
Returns the complete updated time tracking entry record.
