Seconding the recommendation for https://worldtimebuddy.com https://worldtimebuddy.com - it's a really simple thing it does, but it's somehow the only site/tool I've found that clearly displays the timezones in a way that's easy to understand, including the cross-day issues. It helped a lot for me scheduling meetings between both coasts of the US, India, and Australia. It looks like this tool does a similar kind of display, so definitely worth giving a shot. As for this command, I already had go installed on MacOS through homebrew (although I rarely use it in any form) - and the build went fine and the command runs as expected.
