Abstract

A method for synchronizing a distributed application (12 32), comprising the steps: an application backend (12) of a distributed application executed by a server (10) transmits application data packets (14) to an application frontend (32) of the distributed application executed by a terminal device (30) via a communication connection (22) provided by a communication network (20); the application backend (12) transmits a synchronization request packet (15) to the application frontend (32) via the communication connection (22); the application backend (12) retrieves a backend timestamp from a clock (11) of the server (10); the application frontend (32), upon receipt of the synchronization request packet (15), retrieves a frontend timestamp from a clock (31) of the terminal device (30) and transmits the retrieved frontend timestamp to the application backend (12) via the communication connection (22); and the application backend (12) calculates a time offset of the transmitted frontend timestamp from the retrieved backend timestamp and uses the calculated time offset as a synchronizing means; and a distributed application (12, 32) and a computer program product.
