TECHNIQUE FOR CORRECTING A TIME PARAMETER

The invention relates to a technique for correcting a time parameter (115; 125) in a first node subject to a second node. A device aspect of the technique comprises a clock pulse generator unit (110), which provides periodic clock pulses in the first node. A peripheral unit (120) decodes symbols of an asynchronously transmitted telegram from the second node and measures a number (124) of clock pulses during the transmission of a symbol sequence of consecutive symbols of the telegram. A correction unit (130) corrects the time parameter (115; 125) dependent on the relationship between the measured number (124) of clock pulses and the number of consecutive symbols in the symbol sequence. 本发明描述一种用于根据第二节点修正第一节点中的时间参数(115；125)的技术。所述技术的装置方面包括时钟脉冲发生器单元(110)，其在第一节点中提供周期性的时钟脉冲。外围单元(120)对从第二节点异步传输的报文的符号进行解码，并且在报文的相继符号的符号序列的传输期间测量时钟脉冲的数目(124)。修正单元(130)根据测得的时钟脉冲的数目(124)与符号序列中相继符号的数目的比例来修正时间参数(115；125)。
