Sync with GA app at the mobile timing and script

[tcolonel]

Hello.

How I can sync GA app timing at the mobile with PHP script?

In the example I see:

$secret = 'XVQ2UIGO75XRUKJO';
$time = floor(time() / 30);
$code = "846474";

But in the GA app another timing ... And when I put code from GA app its valid. But when time is over in the GA app code still valid.

Thanks.

GA will automatically sync itself to the real, correct time. You should sync your local server's clock manually. Codes might still be valid after a few seconds to compensate for network latency and other minor delay issues.
