-The display clock can follow the local system clock, an NTP server, a PTPv2 (IEEE 1588-2008) master, or SMPTE LTC (Leo Bodnar LBE-1110 USB serial **or** decoded from a local audio input). **OnAirScreen never changes the operating-system clock.** NTP and PTP steer an independent timebase (`time.monotonic()`), so a jump of the system clock does not move the studio clock. LTC may jump, freeze, and includes frames (`HH:MM:SS:FF`). 
- 
-Date, text clock, and AIR3 top-of-hour follow the same wall time as the large clock when the source is Local, NTP, or PTP. With LTC they keep using the system date/time, because LTC has no calendar date.
