1. A method for generating timing signals for operating a wireless terminal in multiple wireless networks each having a wireless network time base, comprising:

  • generating a calibrated slow clock by removing clock pulses from a free-running slow clock and using a fast clock as a calibration reference, the calibrated slow clock having fewer clock pulses than the free-running slow clock;

    converting a plurality of wireless network time bases into a unified time base by generating absolute time values according to values in a counter clocked by the calibrated slow clock; and

    timing events in the wireless networks based on the absolute time values of the unified time base provided by the counter,wherein the unified time base is different from at least one of the wireless network time bases, and the at least one of the wireless network time bases cannot be converted to the unified time base by a synchronization process.
