Puzzle to correlate time from browser to set watch face to same time.

I had to take some time away from this for a while, but I recently came back to it, trying to get the time working correctly.

I tried using the example provided by alexopatin, though I seemed to have some issues with it. I recreated his puzzle setup as best I could, but I am unsure about the first puzzle inside each ‘do something’ container. It looks like it is just text, (in Russian, which I cannot read), but I see the puzzle comes from the “Advanced” section. It makes me wonder if the puzzle is related to javascript?

So the attached picture is the setup I feel is best so far:

It seems to work well most of the time, but it also seems to be incorrect at specific points in the 12 hour cycle. I have noticed that the hour hand jumps an hour ahead, when it passes the 12:00 mark. Also the time seemed correct when I was previewing it locally, then when I published it on the Verge3D network, it jumped an hour. I am still unsure if this is simply due to the cache in my browser, because later I looked at the Verge3D network link on my phone, and it seemed to be showing the correct time.

My concern is that I am providing this example to show potential clients, etc. I need confidence that no matter when they view it, it will be accurate to the actual time. And if I leave it running, it should not over time, become inaccurate.

Here is a link to the current published setup:

I can provide the application data, but would prefer to send it though a private message. Thank you again.
