1. A method comprising:

  • during a first synchronization event, obtaining, by a first electronic device in communication with a second electronic device, timing or synchronization information from the second electronic device;

    determining a time offset between a first timebase of the first electronic device and a second timebase of the second electronic device using the timing or synchronization information;

    adjusting the first timebase with the time offset; and

    at an adjustment time occurring after the first synchronization event and before a second synchronization event, dynamically or adaptively adjusting the time offset based on an estimated timing error for a time period between the first synchronization event and the adjustment time, wherein the estimated timing error is determined without communication between the first electronic device and the second electronic device.
