Do not ask for the time zone, ask for the city. Than use a tool for the task. People are stupid, and they don’t necessarily know the name of their time zone, even during DST.
I used website this before, you just type the city names and it will show you which time is good for which participant: https://www.timeanddate.com/worldclock/meeting.html But I’m pretty sure a lot other websites exist to solve this.
The problem in your story was not time zones, but you didn’t use the correct tool for the task.

It’s not me who didn’t use a tool, it was the other guy.
