I live in Kentucky in the United States, so my time zone is either Eastern Daylight Time (EDT) or Eastern Standard Time (EST) depending on whether or not daylight savings time is in effect. Currently we're using EDT!
I'm back in PST right now, but I was living in EST for 10 years. For a while after I moved back to PST I did keep my time zone on TBT as EST just because it was a little easier to keep track of events hehe.
I do appreciate the fair clock and such things to help us keep time though! I almost feel like it might be helpful for many other site events too as a slightly permanent (but maybe smaller?) feature
I'm in MDT (UTC-6), though in a month it'll be MST (UTC-7). I've never had a problem with my time zone, and I've gotten pretty good at converting my time to other time zones over the years.
