Lady Heather's on-screen clocks "tick" when the GPS time code message comes in. Most receivers send the time code message around 100-250 msecs after the actual 1PPS time. A few (like the Z3801A) send it before the 1PPS time. The Jupiter-T sends it around 1200 msecs after the 1PPS!
Heather applies an adjustment factor to the time in the time code message to compensate for the receiver message delay/offset. If you don't specify an adjust factor (/tsx=msecs), it uses a typical value for the receiver. Normally the time in the digital clock is shown down to seconds. You can see the (adjusted) time down to the millisecond with the "TM" keyboard command. The hand positions in the analog watch display have the receiver adjustment factor, it's just that the clock is ticking when the time code message comes in.
> I am wandering, if anybody else noticed that LH 5.0 watch is little
behind of some other relatively good time source ?
