Show HN: I made a tool to compare time zones

Congratulations on the launch. Looks great! A couple of questions if you don't mind me asking:

1. Why did you build this tool when we have thousands of time zone comparison websites, apps and inbuilt functionality in smartphone time app?

2. Google already does this natively

3. It will be really tough to rank this on Google

4. Do you plan on monetizing this?

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 was thinking of this site as well, showing the different time lines and how they offset according to the time difference. Very neat. Just couldn't remember the domain name.

The design is a bit dated as it's not optimized for higher res screens, everything is quite small. I guess people can zoom in.

How do they make money though? I don't see ads or sign up page for extra features. Running this service since 2011, have to pay for hosting fees etc.

Your link also has an extra feature that the OP does not.

When I open https://www.timezones.digital/ it asks permission to get my current location and then displays the time for my location. And it even got the city name correct. This is great on mobile.

Whereas https://time.fyi/timezones does not currently request access to location and instead uses the location of my IP address. Which in my case is the location of my ISP and not of myself. Using the name of the city my ISP is in, which is halfway across the country from me.

interestingly, that one misnames Rio de Janeiro as "Vila Rio de Janeiro" which is hilarious, considering the Rio metro area has ~12M people, so a bit bigger than my idea of a village

I'm not a fan of the design, tbh. I see no reason why these need to be cards, which actually forces the sliders to be next to each other (rather than below each other or combined into a single slider)

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.

Not a problem if you aren't playing that game.

I've got a few things out three that probably aren't listed anywhere (they won't be anywhere that respects the robots.txt equivalent of “go forth and fornicate”!). They are there for me, friends, family, or to refer people to when relevant. Heck I might even mention one on public forums occasionally either due to relevance or just for a little mild ego-stroke. But I don't care whether or not they are listed in the first page of Google/Bing/Kagi/… so the general public can easily find them.

Admittedly the general public likely aren't even looking for them, I'm sure they are well served elsewhere, but that is beside the point.

Being massively popular doesn't necessarily imply fame & fortune. It might instead be fame and needing-to-find-a-way-to-pay-for-resources-to-keep-stuff-running-under-high-traffic (and dealing-with-stupid-emails-from-people-who-don't-know-which-elbow-they-are-sat-on!).

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.

This is really cool! Found a small bug - when you add a second card, the second card displays a pill with the total time difference between the first card and second card. When you switch the order of the cards by dragging, the pill remains on the same card so it's basically showing the total time difference in reverse. Clearing the cards and starting over with the switched order but by creating each card again results in the pill being displayed on the correct card.

Seems many people have ideas for adding features. But nobody is really talking about whether they are using it in their day to day (or would use it).

My primary use case would be setting up a meeting across timezones, but my calendar app already shows me overlapping times.

Or knowing what time it is for family or a friend, but then that becomes second nature if you’ve been in different timezones for a while.

Or just seeing what time it is somewhere right now, but phones have multiple clocks, or a “what time is it in x?” search answers the question.

If the many suggested features are added, would you use it? How will this help you?

If you work with people across multiple timezones, it's really useful to be able to open a screen with a set of clocks and glance at the time in every relevant timezone.

If I just have https://time.fyi/timezones bookmarked, it seems to remember the timezones that are important to me. Definitely convenient and far easier than doing multiple searches or using a phone's multiple clocks(?).

This site is useful enough and it's a nice execution.

Very nice, very useful. The slider is extremely easy & fast input method which is great. I've encountered an issue with the fonts spacing of hours and minutes - the digits are overlapping: https://imgur.com/a/meoRaJL (Win11, Chrome, Firefox, Edge)

Very clever solution! Would be cool to add a color coding of the time, maybe same way as Apple does sun position in the weather app. So when you scroll time you can see where of all these places the sun is still up.

Fantastic. Thank you.

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

Very useful. Thank you! I’d suggest to place the time above the slider. I’m left handed and I’m covering the time when I adjust the slider.

Very nice. I'll list a feature I've always wanted but haven't seen on timezone converters.

A map of timezones, which will either highlight the location entered, or allow you to select the timezone.

Saves a few keystrokes.

Great work! I've looked for this kind of thing before but found only the usual sea of spam and semi-functional tools.

Yours is really good, simple and clear.

One suggestion I have is maybe show a bit more prominently if the dates end up being different? Could be easy to miss.

Maybe the cards could get background color based on time of the day (e.g. blue for mid-day, dark for night etc.)

Might be useful to have the slider cover 3 days, rather than just 24h. With the single day, New York visually looks to be ahead of London at certain times of day (e.g from 00:00 to 05:00 UK time), because NY is still in its previous day.

Very well designed. I'd recommend saving the current state in the URL parameters, so you can share it (or save the link for yourself).

Also, open-sourcing it would be cool.

Welldone, this is very useful!

From my use cases (order of wantedness):

1. It would be nice to be able to type in a time rather than using slider.

2. A flag to say whether day light savings is in affect.

2. As well as current time what about adding other times in the blocks - I always need to convert 9:30, 15:30, 23:00 into local.

3. On desktop, there doesn't seem to be a reason that 12 and 24 hour clocks could be shown at the same time?

Well done! I'd use this over what's out there. Suggestions: 1. On mobile, it's hard to see more than 2 times without scrolling. I think compress the vertical space more 2. Might be nice to share a link with a configured set.

Weird use case, but some places use 12hr, some use 24hr time. You could likely infer that by timezone name itself?

I know if I get meeting at noon or midnight - I need to triple check everything…

I like the way this tool looks, but I am a big fan of the "row-based" designs from these other tools for comparing time zones.

* Time Converter and World Clock - Conversion at a Glance - Pick best time to schedule conference calls, webinars, online meetings and phone calls. || https://www.worldtimebuddy.com/

And this site has a bunch of great tools for calculating time between days and a bunch of other miscellaneous stuff.

That's really nice and coincidentally I needed such a tool just a few days ago.

If I could make a small suggestion - always mark a few key times on the timeline so a user can quickly guesstimate, say, midday here is 9am there without the sliders.
