A method is provided for assigning a time stamp to a specific data packet which, as with a group of received data packets, is received by a cyclically operating sensor. The specific data packet especially is part of the group of received data packets. The method includes: determining the time of arrival of each data packet of the group of received data packets; assigning a time stamp to each data packet of the group of data packets based on a first reference point in time; determining the time difference between the determined time of arrival and the assigned time stamp for each data packet of the group of data packets to provide a group of time differences; determining negative time differences from among the group of time differences, for the data packets of which it has been determined that the time of arrival preceded the respective assigned time stamp; determining the negative time differences that are not to be classified as outliers; determining a second reference point in time taking into account the negative time differences that are not to be classified as outliers; and assigning a time stamp to the specific data packet based on the second reference point in time.
