Zusammenfassung:	It is provided a method for providing a time reading. The method is performed by a mobile device (2) comprising a secure element (1) comprising a real-time clock (7). The method comprises: synchronising (40), by the secure element, the real-time clock (7) with a time server (3); letting (42) the real-time clock (7) run in the secure element (1); receiving (44), by the secure element (1), a current time request (30) from a time reader (6), via a mobile device (2); generating (46), by the secure element (1), a response, the response comprising a current time reading from the real-time clock (7), and cryptographic verification data; and sending (48), by the secure element (1), the response (32), via the mobile device (2), to the time reader (6).
