There has been for many years now a hack in NTP which allows you to echo off the service so that there is a repeater cursor in the time number stream. We have developed and are in the process of enguaging scientist around the world to contribute by adding time calendars to the system.
Remember if you don’t set the date zone (Which is the PHP Date Zone Codes ie. GMT+0/GMT+0 = GTM+0 or America/New_York — if you don’t set the time zone you want to receive all the current dates including a full Mayan date seed from; then you get the dates of tomorrow.
To See this RSS Feed which is designed to replace NTP as a sourcing as I believe setting someone chronometer should be done from multiple seeds and from their preference of what set the network date can be seen here:- http://time.labs.coop/Australia/Sydney
You can download the source~code for time.labs.coop from: https://sourceforge.net/projects/chronolabsapis/files/labs.coop/time/
This is very useful with a smartphone, or computer, you can use your RSS Feed Reader and that previous time.labs.coop URL to receive time zone tickets which only surface on your profile when you drop/delete them to your feet from the device, this is like dropping a kitana, everyone knows your there.
