  • Publication number: 20130307632
    Abstract: A time base management system facilitates early analysis, detection, and status messages (e.g., early warnings) concerning the operation of time bases in a device. In addition, the time base management system may adapt the time bases in the device according to the anticipated, selected, or actual operating conditions of the device. As one example, if the time base management system knows that a cell phone will switch to a high data rate (e.g., 4G or LTE) operation mode, the time base management system may configure a time base in the cell phone to operate with increased precision or accuracy, or otherwise meet any applicable time base operational profile for high data rate operation.
