Abstract

The disclosure relates to a method for generating a time stamp in a vehicle which participates in a vehicle ad-hoc network. The method includes associating, by giving out the time stamp, an event, which is transmitted in a message, with a clock time. The clock time is generated by updating a global time base that may be derived from a global satellite navigation signal (GNSS). The method includes checking whether a GNSS signal may be received. The method also includes generating the clock time based on a local time base if an insufficient number of global satellite navigation signals for deriving the global time base is available.
