Methods and systems for performing timekeeping by a data processing system are disclosed. To perform timekeeping, the data processing system may include an oscillator that provides signals upon which time keeping is based. The signal provided by the oscillator may be impacted by the temperature of the oscillator. During periods of time when the data processing system may communicate with other devices, the data processing system may perform cooperative timekeeping synchronization through exchange of data with the other devices. During periods of time when the data processing system may not perform cooperative timekeeping synchronization, the data processing system may perform independent timekeeping synchronization by attempting to thermally stabilize the oscillator.
