Under the Zoho Projects API documentation for Timelogs, there is an option to get all user time logs, but not to get time logs from a specific date range. Upon further research I learned that Zoho people's API has that functionality. It would be great to add that functionality to Zoho Projects rather than going to a completely different service to do this. This is forcing users to overdevelop for functionality that is already present in another service.
