I’ll start with a couple I’ve found for keeping up with atomic clock time, but this question isn’t limited to timekeeping, it can also relate to celestial events, weather, etc…
I do like the sleek and streamlined time.ms site, but according to their whois data, they only started that site a couple months ago, while time.gov has been around since 1999.
Long standing sites are preferable, but either way, what other live data sites do you people recommend?
Yes indeed, they actually host time.gov, but open up the nist.gov main page and check the notice at the top. The US done cut much of their funding so most of the site won’t be getting any more updates, at least not anytime soon… :(
