harvest_create_time_entry
Create time entry
Create a time entry. Requires project_id, task_id and spent_date. Provide `hours` to log a specific duration; OR provide `started_time` (+ optional `ended_time`) for a timestamped entry; OR omit both to start a running timer (on a timestamp-tracking account). Use harvest_list_project_assignments to find valid project_id + task_id. Harvest REST: POST /time_entries. WRITE — creates data.
