I have built Cuber (https://github.com/cuber-cloud/cuber-gem) a few years ago as a replacement for Heroku and now we use it to deploy all our Rails applications on DigitalOcean Kubernetes. Extremely lower cost, better performance, less bugs, better support...
I have moved all Rails apps away from Heroku in the last years. It was great 10 years ago, but then became expensive, full of bugs and with terrible support. All our Rails apps (Pushpad, Newsletter.page, etc) are running on Cuber gem + DigitalOcean Kubernetes... In the last years we achieved 100% uptime (five nines), zero subtle bugs and huge cost savings.
In any case those clocks are all extremely inaccurate, even if AI could build a decent UI (which is not the case).
Some months ago I published this site for fun: https://timeutc.com There's a lot of code involved to make it precise to the ms, including adjusting based on network delay, frame refresh rate instead of using setTimeout and much more. If you are curious take a look at the source code.
