Abstract
A method and apparatus for determining relative modification times between a local file stored on a local device and a remote file stored on a remote device are disclosed. The method may include sending, from the local device to the remote device, an inquiry requesting a remote modification time for the remote file on the remote device and receiving a remote modification time at the local device from the remote device. The remote modification time is determined by subtracting a time the file was modified on the remote device from a current time obtained on the remote device. A local modification time is calculated by subtracting the time the local file was modified on the local device from a current time on the local device, and the local modification time is compared to the remote modification time.
