3B-http_sntp.js

This library provides a simple means to synchronize a client browser with your server. The time adjustment should be good enough for accuracy within a second.

The library will send a GET request to a web server and expects a simple text string as a response. The GET request URL will contain 1 URL parameter with a key name of 't0'. This corresponds to the time the request left the client for the server. The server should respond back with a response string in the body with a format of:

t0=1234:t1=1234:t2=1234

t0 is the same parameter from the request paramter.

t1 is the time that the server receives the reply. This number should be as close as possible to the time the server actually receives the request.

t2 is the time that the server sends the response back to the client. This number should be as close as possible to the time the server actually sends the response back.

All the values, t0, t1 and t2 are numbers that represent the time in milliseconds since the epoch time of 01/01/1970 at 00:00:00 UTC. This is the standard epoch time of Javascript, Unix and various other systems.
