1. A method for determining in a system comprising an m-bit time counter, whether an event-occurrence time (etn) lies after a predetermined timeout-value (te), said method comprising:

  • a stamp readout step for reading out of a time-stamp memory a stored time-stamp value (stn);

    a time-difference determination step for determining the time-difference (Δ

    tn) between said time-stamp value (stn) and said event-occurrence time (etn); and

    a timeout-determination step for determining whether said time-difference (Δ

    tn) is larger than said predetermined timeout-value (te),wherein said event-occurrence time (etn) is represented by a subset of bits of the m-bit time counter, said subset being determined by a plurality of parameters, said plurality of parameters including any two of a lower bit position (w), an upper bit-position (u), and a subset width (n),wherein (u=n+w),wherein a predetermined timeout period comprises said predetermined timeout value (te) multiplied by 2w clock cycles, andwherein said lower bit-position (w) is predetermined and dependent on said predetermined timeout-value (te).
