Sounds like you have too small TV or you too long viewing distance.

The differency between FullHD and 4K is very noticeable with THX-recommended viewing angles. I watch 98” from 3 meters.

Interesting idea! But I think such upgrade would take years, if not decades, to get widely adopted.

The old JS Date API is far from perfect and I'm happy it being replaced, but part of the problem is various string-based formats and people being sloppy using them. Not to mention general complexity in time/date concept with timezones, summer time, leap seconds, etc.

For string format, just stick with ISO 8601. If you need to parse less-standard formats, use a robust library of your choise. The standard library should not try to support parsing zillion obscure formats. Outputting localized / human-readable format should be a responsibility of localization API anyway.

I also think that many libraries/APIs involving formatting things have some US centric design limitations, i.e. tendency to treat US formats as native and international support is often a bit after-thought. Especially with older stuff like the JS Date API.

Care to share what driver board you have used?
