Abstract
A computer-implemented method for managing a real-time clock having a drift and being embedded in a portable tamper-resistant device, which receives applicative data when performing a banking transaction with another device. comprises a step of extracting a time from the applicative data, the method also includes a step of compensating the drift by updating the real-time clock based on said time.
