Hi,

I need to calculate the latency means time difference between the two user machines the scenario is:

1. App 1 publishes stream
2. App 2 play the stream published by App 1

Now in App 2 I need to show the time difference between the App 2 and App 1 time.  
Say if current time on App 1 is 10:46:30 and on App 2 it is 10:50:20 then need to display the difference. How to send the time value to App 2 from App 1 as time zones for the two users may be different.

Any help appreciated.

Thanks
