System for data transfer

A system for data transfer between a server and a respirator, wherein the respirator comprises a source for breathing gas, at least one interface to enable a data transfer, a device for determining data, a control unit, a memory, and a timer unit for specifying a system time, wherein the respirator is configured to give the data a timestamp, to store the data and to transfer the data at a later point in time, wherein the timestamp is designed so that it cannot be adjusted, or can only be adjusted to a limited extent to a tolerance window, wherein the system is configured to carry out a comparison of a system time of the respirator with a server time of the server on the basis of the timestamp when the data transfer is started, wherein the system time is manually adjustable before the respirator is logged into the server, and wherein the server is configured to assess a manually adjusted system time before a login at the server and to compare same with the server time.
