SYNCHRONIZATION OF SYSTEM TIME IN ELECTRONIC DEVICE
First Claim
1. A method for synchronizing a system time in an electronic device, comprising:
- when the electronic device is executing a boot process, disabling an external time obtaining function of the electronic device for obtaining an external reference time, obtaining an internal clock time and synchronizing the system time of the electronic device with the internal clock time; and
when the electronic device has completed the boot process, enabling the external time obtaining function to obtain the external reference time.
