Abstract: A device for correcting a time parameter in a first node in accordance with a second node is provided. The device includes a clock pulse generator unit configured to provide periodic clock pulses in the first node. The device further includes a peripheral unit configured to decode symbols of an asynchronously transmitted telegram from the second node and to measure a number of clock pulses during the transmission of a symbol sequence of consecutive symbols of the telegram. The device also includes a correction unit configured to correct the time parameter as a function of a ratio of the measured number of clock pulses and the number of consecutive symbols in the symbol sequence.
