Clock fixable?

[pbelbin]

I'm trying out 'ontime'.

Looks interesting and useful.

Here it comes:

But, during testing, I'm finding that when I have the Docker image (latest build) on a windows machine, and I have NTP (Chrony) configured within, and seemingly the terminal shows a fairly good correlation with what the https://www.time.is shows, that ontime's browser clock is not keeping good sync.

Seems like it's kinda free-running and periodically resyncs, and between those resyncs, the time slips further and further behind.

So, the clock kinda 'jumps' back into sync for a moment, and thereafter, it progressively falls behind, until the next 'jump' back to correctness.

For a tool that tries to keep everything running like clockwork, this seems to be an odd behavior.

Can it be fixed somehow? Is there something I'm supposed to do? It kinda looks broken to me.
