I came across this the other day, it's pretty elegant and basically solves the problem. Comes in handy when you have eg a call with people in >2 timezones. https://www.timeanddate.com/worldclock/converter.html

I use https://time.is (Choose any location.) Does other conversions and stuff, but much more elegant and simpler than your link. Also good for setting your clock

There's also https://www.whattimeisitrightnow.com/ if you like a longer and harder to remember URL.

Yep I use this for setting my mechanical watch every morning, great website apart from the clock text is relative to window width, so I can't zoom out if the window is too short, I literally have to resize the window width to see the time.

That's an interesting morning routine. Why do you do so (do you work in 'measurement' industry?)?

you can see the traffic with a quick glance at the map app before leaving, but that's a pretty weak excuse anyways. you and i both know that there are people that need those turn by turn directions for reasons.

It feels like you have a bit of superiority complex against people who use GPS. What a weird thing to feel smart about.

Maybe OP doesn't travel a lot. Or is a taxi driver :)

Did I miss something in this article about time zones?

I missed the launch because when I woke up, I read the launch time quickly before being caffeinated, and did not do the math correctly. So when I sat down to watch, I realized it was an hour earlier. Nothing about the TFA, just sharing my misfortune

I quite like Next Spaceflight

https://apps.apple.com/au/app/next-spaceflight/id1448055760

Although it shows launch times in GMT, notifications are in relative time.

Strictly speaking for American contractors, I'm 99% sure that is not true. If you have any contract with the government for space stuff, all of your workers have to be citizens. I'm not even sure they'd let a permanent resident work there because of ITAR.

Lol. Not even. What about Musk. He is not born in US

He became a citizen

time.is is clearly simpler in display on the splash page.

timeanddate.com has a lot of depth to it, it's been about for many years and has a back catalog of odd edge cases and pages of good technical explaination.

Its appearence can be customised.

What did catch my eye was I believe time.is may have read my timeanddate.com config cookies and displayed times for my custom locations ...

Which is interesting (and I'll have to circle back and check).

Mechanical clocks (like all clocks . . .) drift.

For two centuries mechanical clocks and watches have been regularly wound and reset.

Ports traditionally had a noon day canon and ball drop down a pole (like a flag pole) for ships in the harbour to set their onboard clocks to (for navigational use in determining Longitude).

Watches frequently have bimetallic strips (two sided) with metals that each expand with a differing coefficient to counter effect for rate of 'tick' with respect to tempreture.

Ships at sea required triplets of clocks with mechanisms that countered for pitch and roll accumulation.
