Dozenal time is now stable, accurate to within about 1 second. A commit/pull request has been registered.

Overnight, when the watch has no use but of course still runs, sometimes it wakes up to being a bit behind. But soon it fixes itself, via GPS time.

let wait = 4167*(1-(x%1));

Any variable that is % modulo operator with 1 will output 0. So that code is saying, 4167* (1 - 0) ... which is equivalent to 4167 * 1 equivalent to 4167.

let wait = 4167

Am I wrong?

```
x =864*dt.getHours()+14.4*dt.getMinutes()+0.24*dt.getSeconds()+0.00024*dt.getMilliseconds();

let wait = 4167*(1-(x%1));
```
This is getting the fractional part of x. So if x is 456.123
The statement becomes.
```
let wait = 4167*(1 - 0.123);
```
So its working out a value for the next timer call.
