The invention relates to a method, as well as a device and a computer program, for monitoring a first time base of a first communication device and a second time base of a second communication device with the aid of a computer. In a first sequence, Christian's algorithm is used in measurement steps (n) to calculate time offset intervals of a time offset between the time bases. In a second sequence, the maximally possible drift (Ωo) of the time offset is ascertained multiple times for two measurement steps (n, n+x) while taking into consideration the lower limit of the time offset interval for the previous measurement step and the upper limit of the time offset interval for the subsequent measurement step, and a minimally possible drift (Ωu) is ascertained while taking into consideration the upper limit of the time offset interval for the previous measurement step and the lower limit of the time offset interval for the subsequent measurement step. The upper limit of a drift interval (CDW) is calculated while taking into consideration the maximally possible drift, and the lower limit of the drift interval is calculated while taking into consideration the minimally possible drift. In a third sequence, the lowest upper limit is defined as the upper limit of a resulting drift interval (RCDW) for the relative drift from multiple drift intervals (CDW), and the highest lower limit is defined as the lower limit of the resulting drift interval (RCDW) with advantageously narrow limits for the relative drift.
