If there's a particularly good article, we can swap out the URL above. Edit: beefman suggested the nasa.gov page (https://news.ycombinator.com/item?id=23364975), so we'll put that up pending any better suggestion. The submitted URL was the livestream https://www.youtube.com/watch?v=bIZsnKGV8TE, which was fine while it lasted, but is now of the second freshness. Submitted title was "SpaceX and NASA: Crew Demo-2".

"Second freshness - that's what is nonsense! There is only one freshness - the first - and it is also the last. And if sturgeon is of the second freshness, that means it is simply rotten."

livestream still relevant? Docking with ISS tomorrow morning? All the tests they are doing?

Yes, live broadcast until docking at 10:30am EST.

To clarify, it's "EDT" not "EST":

Fyi that "Daylight Saving Time" instead of "Standard Time" is in effect in case someone miscalculates it by 1 hour.

Out of curiosity, how do modern systems handle DST outside its seasons e.g. “12/31 21:15 EDT”?

I think on most Linux systems a time string in a specific timezone is just a visual representation. Internally, times are kept as a number of seconds from 1/1/70 UTC midnight (with leap second adjustments if needed). When a user wants to convert to/from a timezone it is a simple addition for the timezone offset. EST adjustment is always 5 hours, EDT always 4.

You could in principle warn users that they are asking for a strange time, e.g. the one you indicated, but if the user wants to see it, why not.

I know on ubuntu servers i had to revert any DST/timezone settings and just keep everything in UTC. Because the systemd daemon for time didnt respect DST changes and would break services like kerberos.
