Abstract

Disseminating the standard time in Egypt through internet is introduced in this paper for the first time. Establishing a web-based clock is the first step of the time dissemination process. The standard time that is disseminated to users in Egypt is synchronized to the Egyptian time scale (Coordinated Universal Time of the National Institute of Standards UTC(NIS)) to be traceable to it. Enhancing the performance of UTC(NIS) is firstly discussed before using it as the main source for the synchronization process. Also, the accuracy and reliability of the disseminated time is further enhanced by proposing two alternative synchronization sources to be used in the absence of the main source. This research aims to develop a traceable and reliable dissemination of the standard time in Egypt using web-based clock. It investigates the benefits, challenges, and potential solutions associated with implementing clocks on the NIS internet portal to provide accurate and accessible local time information in Egypt. The results emphasize the need for individuals and organizations operating in or dealing with Egypt to consider the time difference when scheduling time-based events or communications. They should also utilize recent technology tools as portal and others to facilitate effective planning and coordination across different time zones and maintain clear communication with counterparts in different time zones for successful global operations and collaboration.
