Thanks for sharing, it works very cool
This is extremely useful. Thanks for sharing. Are there future features planned? It could be a big thing.
What else would you like to see? I have some other time related tools that I will be launching but would love to hear what you have in mind.
- Show the timezone name/descriptor if I select a city (yes, it already says 'GMT+X', but it would be helpful to have the local timezone name of that city as well) - Somehow select a time for a different day. E.g. if I want to compare the times for the 22nd of October 2024 instead of today (Countries/Cities/Regions swap timezones x-times a year, on different days)
I was thinking it would be cool to add another slider for day of the year. That way you can see how the differences change as local timezones roll through their own daylight savings time or other adjustments. For example, right now Asuncion Paraguay is +3 hours ahead of Chicago U.S. but in April it will be only one hour ahead.
Wow, what a nice tool :) bookmarked!
its very well designed, bookmarked
Very useful!

It would be nice to be able to share a set of timezones by sharing a URL with parameters.

Yeah, time.is supported that for a long time and was extremely useful for me.
I was going to say the same thing. The lack of this feature prevented me from sharing it to my whole company
Looks great, unfortunately I am having challenges using it on iPhone Safari: trying to engage the sliders moves the cards around instead.

Can we drag the boxes to re-order?
Yes, you can.
I’m unable to drag the cards on iPhone.
Ah that was intentional, it disables the sorting on smaller screens. I am working on some UI refinement for smaller screens and will re-enable sorting after that.
I've always been a fan of the https://everytimezone.com interface, which seems like it may have been acquired at some point. Still works brilliantly though!

Yes! I've been looking for this one and couldn't find it! Thank you. Google is useless for finding stuff like this now.
Also might be useful to some: in Google Cal, you can show a secondary time zone on left hand side. Mine shows PT and CT for example.
I depends on this, but Google Calendar only lets you add a second time zone. They don't take up much space, I'd love to have 3 or 4. Has anybody figured out a way to do that?
This is a great tool. Thank you. As an international student in US with a lag of 10-12 hours with my home country, this will be very helpful in scheduling calls.
Very well designed

Can I edit the name of the cities? As in I want to label as San Francisco instead of "Los Angeles"

The reset button doesn't really explain to me as it will reset to current time.

There’s a lot of dead space. Maybe condense it so more timezones fit on the screen.
I actually quite like the amount of dead space, as most time conversion tools I have used have been filled to the gills with information whereas I am typically only looking for one or two specific data points. To be honest, with many time conversion apps I often even struggle to distinguish a meaningful header, main content, and footer as they will often resemble some sort of industrial ticker. I know, different tools for different purposes, but that is exactly why I like this: it achieves simple comparisons simply.
I’m not saying add more things and information. I’m saying the opposite - remove things (white space) so I can look at more than three timezones changing (which is my use case as I run a ticketing site with venues around the world).
Feature suggestions:

- 12/24 hour setting should be detected based on browser locale.

- Colon symbol is broken on Firefox + Chrome for me in Linux (Shows U+FE55 symbol).

- Ability to toggle showing all cards in a single column layout so you can see the sliders position relative to each other more easily.

Yes, I'd prefer a single column like the experience on mobile
Fantastic. Thank you.

Any way to "pin" the current time so it acts as a live world clock?

If you're one of those "give me a terminal or give me death" master race kind of person, then I have a little shell script I use for this:

  % tz
  US West        18:39 -0800 PST
  US East        21:39 -0500 EST
  UTC            02:39 +0000 UTC
  Ireland/UK     02:39 +0000 GMT
  West Europe    03:39 +0100 CET
  New Zealand    15:39 +1300 NZDT
  
  Current        02:39 +0000 GMT
  
  % tz 18:00
  US West        10:00 -0800 PST
  US East        13:00 -0500 EST
  UTC            18:00 +0000 UTC
  Ireland/UK     18:00 +0000 GMT
  West Europe    19:00 +0100 CET
  New Zealand    07:00 +1300 NZDT
  
  Current        18:00 +0000 GMT
I find it's pretty convenient anyway.

https://github.com/arp242/dotfiles/blob/master/local/script/...

I use something similar, but I use -d "$*" instead of -d "$1" so I can do

    $ dates 4 hours ago
One of two times "$*" had been useful
I didn't know date supported that – can still do that with "tz '4 hours ago'".

For me the most useful part is being able to quickly translate things like "let's do a video chat at 3pm PST" to something that makes sense, which is why it had the second argument to set the timezone.

bug report: Apia shows as capital of American Samoa
I've been a big fan of worldtimebuddy[1] for a long time. I book a lot of meetings across timezones and it's makes it very easy to see when a good time for a meeting would be between sydney tokyo and miami as an example

[1] https://www.worldtimebuddy.com/

Out of curiosity, would you prefer to see all the options laid out so you can quickly scan which ones would be optimal? Or would you prefer to click a button and then it just schedules the meeting for you?
i have always only knew about https://www.worldtimezone.com/

it has a nice world map, but its call planner feature is simpler than some of the alternatives mentioned here.

Great UI design; clean, intuitive, and useful. Thank you for this!

On a side note, I'd really like to know what broken mechanism aggressively downranks such quality community submissions. 67 upvotes in 2 hours, and only ranked 9th. Meanwhile, another post with fewer upvotes in more time is ranked 2nd. Something is very wrong here. I'd love to see more posts like this one, and fewer standard blog articles that are hitting the front page for the third time in five years.

I'd bet you will never find the answer to this.
Nothing is wrong here in my opinion
What is right about it? He explained the faulty algorithm.
There is an answer to your question [0]:

"The basic algorithm divides points by a power of the time since a story was submitted. Comments in threads are ranked the same way.

Other factors affecting rank include user flags, anti-abuse software, software which demotes overheated discussions, account or site weighting, and moderator action."

I love it. Thank you for making it
