I wrote a console based tool based on a similar idea, it shows city-based timezones: https://zeitzono.org/

Unlike hTime, Zeitzono (currently) doesn't offer any meeting suggestion times, it's up to you to figure out when to schedule. That problem turned out to be kinda hard when more than a few cities are taken into consideration, so I never really added it in. (You do get to shift the clock to find the best time though.)

All in all a nice tool. My only suggestion would be maybe to add some more cities to search. I couldn't find some that I tried. Otherwise people have to mentally shift to the closet big city/state (e.g. Gainesville, FL, US -> Orlando/Tampa/Jacksonville), which may be a problem if you are not familiar with the area.

Also, it may be nice to add some aliases (eg. Bombay for Mumbai), because some places still go by their older names and not everyone has switched to the newer official name.

Thanks! What cities did you try? I'm happy to add them. And cool idea about the aliases, if you could give me some, I'll add them too.

GeoNames (http://www.geonames.org/) offers a downloadable database of cities with more than 15k population and their time zones. They list aliases as well. That's what Zeitzono uses. Just use that.

(You don't have to use all the listed cities if it slows down the hTime web app, just pick some minimum population threshhold (eg. every city larger than 100k people) and use those.)
