Abstract: The present invention relates to an apparatus, method and system for synchronizing time. The method includes: extracting line clock frequency information from an input line code stream, and extracting a time synchronization packet from a packet stream corresponding to the input line code stream; sending the input line code stream after extracting the line clock frequency information and the time synchronization packet to a packet switching device; receiving an output line code stream sent by the packet switching device; and calibrating local time according to the line clock frequency information and the time synchronization packet, recovering line clock frequency information of the output line code stream according to the calibrated local time, and inserting a time synchronization response packet into a packet stream corresponding to the output line code stream. In this way, the time synchronization network may be deployed without requiring the packet switching device to support time synchronization.

Abstract: A Chameleon graphical user interface (GUI) is adaptive to a display environment of a requesting application. In one embodiment, a process includes, but is not limited to, receiving a request from a requesting application, the request indicating a display environment of the requesting application; in response to the request, receiving a document from a system hosting the document, the document having a first display; and transforming the document from the first display style to a second display style, the second display style being associated with the display environment of the requesting application.
