I hate when I make the noob mistake of getting the timezone wrong and showing up an hour late like what I did today


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


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?)?


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.

I think for me it's just part of the fun of owning a mechanical watch. Yesterday I got to increment the date from 31 to 1! But also it's useful having accurate time on my wrist and its drifts a few seconds every day (like any mechanical watch).


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).


The default alternatives are LA, New York, London, Paris, Kyiv, Beijing, and Tokyo.


Cheers for that, your comment reminded me to check.

They're regional defaults - I'm getting Adelaide and Sydney thrown in as I'm in Australia .. and a few Asian cities also, along with London etc.

It's close but not quite my Timeanddate customs - I specifically use Toronto for the TSX time.

I guess they're not looking for competitors cookies after all :).


It’s also not possible for them to read the cookies of other domains without those domains setting cookie access control that explicitly allows it.


That's something I 'knew' in theory .. but as I'm back end numerical geophysics coder that avoids web UI as much as possible I frequently lag on the latest sneaky end runs in practice.

Nice to know that this is still the case - but always worth checking.


Yeah, the security of the web depends on it so it’s unlikely to ever change.

Your session tokens that give you access to a website after you’ve logged in are stored in those cookies. If another site could read them, they could use them to access your email, etc.


Why no UTC? I guess London may be the same, though I’m unsure about DST?

The launch wasn’t listed in UTC but in its local timezone? That is odd.


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


I can also recommend https://www.worldtimebuddy.com/

It's surprising how much ads all these tools show though.


yeah, sorry, i won't be visiting some website just to do timezone conversions. i'll just double check my work next time. to me, that's like the people that need to use GPS navigation to go to the same location they've been to more than once.


Well, navigation also shows you traffic information which is useful to choose the best path and to know at what time you will arrive.


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 :)


Actually, I grew up in a time where we learned how to read and use maps (think Boy Scouts without being in the scouts). It’s a skill like anything else that takes practice. Using GPS nav is not practice. I’ll use the map app to look at the route, pick out familiar references, then uses those as waypoints. “Three blocks past majorStreetName, turn right” type of things.


So you "learned how to read and use maps", and that's a reason to not use GPS, but you won't visit a time zone website despite not having learned to do time zone conversions? I could see how the former is justified rationally but the latter doesn't seem to be.


Like you’ve never forgot to carry the one or put the decimal in the wrong place. Where you come off with that rationale is beyond me


yeah, sorry, i won't be visiting some website just to do timezone conversions.

I'm surprised to find that units doesn't handle this.

I wonder if there's another CLI tool that does.


/usr/bin/date converts using the https://en.wikipedia.org/wiki/Tz_database, though it's clunky.


I just Google like "7pm EST" and it returns it in my local time.


I empathise. My parents and I did that once.

Before all the clocks were self-updating, we missed the change to summer time, which happened to be the day we'd arranged to meet sister and grandmother at a restaurant for Easter lunch…


Windows clock can show up to 3 timezones (system + two). I set one to whatever event I want to track, that way I'm sure I don't mess it up due to summer/winter time and whatnot.


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.
