AChS-1 clock wired working behavior

[JohnnyHo]

I brought an AChS-1 clock on ebay lately, so I play DCS to practice on how to use it, and I found all the AChS-1 clock equiped in DCS modules are not working with same behavior，so I made a list on these wired working behavior of all the  AChS-1 clock that equiped in DCS module.

1. In Mi-8, the AChS-1 clock works perfectly as the manual says and like the real life video in youtube(https://www.youtube.com/watch?v=Vn9LUJiWBNU&t=48s).
2. In Su-25A，Mig-29A & S, the scond hand needle of the clock is not moving after the mission start.
3. In Yak-52 and Mi-24, the markings inside the flight time mode indicator window of the clock are White, Black and White-Black, not like the Mi-8's clock with White, Red and Red-white markings.
4. In KA50 and KA50 III, the markings inside the flight time mode indicator window are Black, Red-Black and Red, not like the Mi-8's clock with White, Red and Red-white markings.
5. In Mig-21, the markings inside the flight time mode indicator window are Black, White and Black-White, not like the Mi-8's clock with White, Red and Red-white markings.
6. In Mi-24, the markings inside the flight time mode indicator window are Grey, Black and Grey-Black, not same as the Mi-8's clock with White, Red and Red-white markings.
7. In Mig-15, Mig-19 and L39C & ZA, the scond hand needle of the clock is not moving after the mission started, but it start to move when I press the right knob. And inn L39C & ZA, the stopwatch time span is 30mins, not 1hr like the Mi-8.

So I don't know are that the minor differeces between the AChS-1 clock production batches or are that bugs?
