Tempus Custode
En GPS-tidrapporteringsapplikation
This paper describes Tempus Custode, a smartphone application with which the user may register working hours and travel time during the work day. The application communicates with a database via a server. The data stored in the database may be manipulated using an administrator tool, mainly for the composition of time reports. In this way, the user?s task of time reporting his day is greatly simplified.The application is able to automatically discriminate between work time and travel time, as it continuously fetches positioning data from the smartphone GPS receiver. There is a personal integrity issue inherent in this operation, because an employer may supervise an employee?s position during the work day. The application may still, with some qualifications, be in accordance with the Swedish Personal Data Act.The Tempus Custode project comprises one tentatively complete application that runs on all modern smartphones. A simple server has been implemented, together with a database. The administrator tool has not been developed. Data in the database are otherwise viewed and manipulated.The results of testing the system have been satisfactory, leading the authors to claim that the project?s objective has been fulfilled: Tempus Custode can significantly simplify the work day of the user, by offering simple, semi-automatic, GPS time reporting.
