I try to get time from server where I connect. (I need PERFECT sync ~diffrence max 1 second)

This clock is visible at bottom of page , but this clock is live (JavaScript) Javascript - get current server time, and adds connection time to page.

This code runs if supportPerformanceApi is false (variable in JS on this page )

    this.time=new Date().getTime()

else

    this.offset_from_server=Date.now()-performance.timing.responseStart;
    this.offset_to_server=performance.timing.responseStart-
                          performance.timing.fetchStart

But without javascript I get default time + connection time.

(Clock starts from 02:00:00 i think 02:00:00 bcoz GMT +2)

I want only to get server current time and I can make own thread to control actual time (by adding to current server time , "one second per second")

Have you considered [NTP](http://en.wikipedia.org/wiki/Network_Time_Protocol)? It's very hard to tell what problem you are trying to solve or what your constraints are. – Alan Stokes Aug 03 '14 at 15:53
Alternatively, the HTTP headers from the server include Date:, which tells you the server time to 1s precision. – Alan Stokes Aug 03 '14 at 15:54

Is there a good NTP class protocol? .. I found this [link](http://www.codeproject.com/Articles/461/CSNTPClient-An-SNTP-Implementation) but this need to include MFC lol ... – Thomas Banderas Aug 04 '14 at 00:26
