NTP Check

OnAirScreen checks the local (displayed) system time to an external NTP server from Those serverpools are unreliable from time to time and may lead to NTP warnings. You are advised to change to a stable or even local NTP server.

NTP glitches on Windows

By default Windows 10/8/7 syncs your system time with Internet servers on a weekly basis. This may lead to a wrong system time and a display of the wrong time in the OnAirScreen. Here is some tips how you can set the update interval. Recommended is something between 15m to 1h.
