You don't need to change times due to other peoples timezones, there are 24 in fact, and itch always shows the dates in which an event/jam will start, there will always be the 3 cases where there is people both before or after your timezone if your in the middle somewhere. There will be people basically a full day behind you if your like the 1st timezone, or there will be people ahead of you if your the Last timezone, as there is 24 hours and each part spans a part of the day. (GMT) as in General Mean Time is a very good one, just state the obvious and Itch will also state the obvious to those in other timezones no biggie if this was like a locally locked Jam event only then time does matter as everyone is same time. (I'm EST Time) but I ain't asking for an adjustment cuz my time will be off. Just do what works for you, your the host so you need to be there to Moderate, Guide, Help, etc. The people in this community during. ;)
