It would be nice to have a permalink to a version with my customized list of time zones. I imagine it would be useful to send it for recurring meetings with the same set of persons.

#164Very nice work! Couple months ago I built a Chrome extension solving the same problem but little bit differently. New tab displays the timezones + a nice picture and weather of the cities you choose. It's completely free if anyone is interested: https://chrome.google.com/webstore/detail/cityzen/hfdldnggnf...

Wowzers I love these one-hand 'slow' watches! https://svalbard.watch/pages/Svalbard_24-hour_watches.html I hope I can get Pole Clock on Apple Watch, wish they allowed custom watch faces!
Nothing comes close to the convenience of an Apple Watch.
First, you can add custom cities to your Apple Watch, so you can see the time in e.g. Dortmund (which has my relative) as opposed to Frankfurt (which is a big city that happens to define the time zone but has no relatives). With mechanical watches, you are limited to a selection of cities that might or might not be relevant to you.
Second, the DST renders any mechanical watch incorrect for at least half a year. One of my relatives is in Brazil, where they have DST in their summer (Dec-Feb), so mechanical watches are incorrect for almost a year (except for a couple of weeks around the DST shift). Again, Moscow has moved permanently to summer time. Apple Watch has all this covered.
Third, most GMT watches with 24-hour hand have a "night/day" bezel (black-grey aka "Batman", or blue-red aka "Pepsi"), but they all separate 24 hours into a 12-hour period of "day" (6am-6pm) and "night" (6pm-6am). Apple Watch shows the actual daylight and night time at any day of the week (so the "bezel" is split unevenly).
Mechanical watches are good at many things but being able to reliably track several DST-observing timezones is not one of them. In this, nothing even comes close to the convenience of an Apple Watch.

#167Shouldn't there be two minute hands if you add LA and India (PST and IST)? The minutes are offset by 30 mins in this scenario.
Came here looking for a comment suggesting these discrepancies. I was not disappointed. See also: “Falsehoods programmers believe about time” https://infiniteundo.com/post/25326999628/falsehoods-program...

#168Instead of dividing by two equal halves day and night, make this dependent on sunrise and sunset of the location, would be helpful to know at a glance the actual day hours and night hours
I built a clock that does just that. It also shows twilight times and the position and phase of the moon: https://sunclock.net/

I tend to use worldtimebuddy.com as a very practical way of representing timezones when scheduling things. As cool as this pole clock is, it's not as useful to my mind as the more linear representation worldtimebuddy.com uses.
