hello: You must sync your PC's date and time with Cesium Atomic clock. Use this very small and tiny program written in PHP.

hk: Time to dust of my GlobalDateTime (GDT) article. Just a quick explanation.

GDT uses the Modified Julian Date (MJD) that is also carried with the Boulder signal. The offset between the MJD and the multi-dimensional RDBMS (mdRDBMS) internal date is constant so adapting GDT to the mdRDBMS environment is simpler than adapting it to other environments.  For the sake of those other environments that are crossposted, mdRDBMS applications store dates as an ordinal MJD like number except that the epoch (day one) is 01JAN1968.

As the name implies, GDT is a single attribute for both date and time like 51550:43200 which is 12:00 (noon) on 17JAN2000 (don't hold me to the date). The purpose of GDT is simplifying e-commerce by basing all transactions on GDT. Unlike other existing and proposed systems, GDT is kept in the background while software and/or firmware convert GDT into any kind of cultural and/or time zone format. Except in the Greenwich UK time zone, each computer would therefore have an internal (GDT) date/time, an external date and an external time.

The major goal of GDT is to have computer manufacturers install an atomic clock time module so that syncing is not nearly a critical issue as it is now. As has been noted in these posts, PC time is highly inaccurate. However, if all the PC's in the world where constantly syncing over the net, the cost of that syncing would be much greater than installing an accurate clock in all future computers. As an analogy, a 30HP motor uses about $22,000 in electricity to operate constantly for a year. Still people tend to focus on the cost of the motor, rather than on the cost of the electricity.

I have asked alavoor to post my GDT paper to the same website http://phpclasses.upperdesign.com/browse.html/package/285

Until that happens, anyone is welcome to request a copy via e-mail lastnameatearthlinkdotnet
