Beschreibung
Zusammenfassung:	The invention relates to a device (110) which comprises a temperature sensor (111) and accesses an external time or frequency reference (121; 130) in order to retime an oscillation frequency of a VCTCXO oscillator (113). The device determines a variation in the ambient temperature of the VCTCXO oscillator over a time range that is predetermined using measurements from the temperature sensor, and adjusts a frequency or a rate of access to the external time or frequency reference in order to obtain time or frequency information for retiming the oscillation frequency of the VCTCXO oscillator depending on the temperature variation determined.
