Thanks for the reply.
I ask because it is very convenient and solves a ton of problems when you have multiple things scheduled in different time zones and travel to multiple time zones and don't want everything switching with the time update.
Floating time zone is an option on MacOS and it is very useful.
I don't see it as an option to enter on the iOS calendar but it does show up when you enter an event via MacOS.
Any idea how to input an event using the floating time zone via iOS without paying for an expensive 3rd party calendar app?
