EST == Chicago but should not

See attached screen in case it is transitory. This was definitely not happening a while back since I personally use that conversion a lot. Could you improvements have affected this?

fixed for now by making EST actually mean the same as EST5EDT and Eastern

Here's a visual demo:
Having researched it, EST is weirdly built into the Olson db that we use (via the tzinfo gem). No other standard time is built in (PST, CST). There is also EST5EDT (which is the same as US/Eastern).
If we want to remove it, it's a bit of work (first time we've wanted to remove from the Olson supplied list, rather than add). Ideally it would be possible to add some kind of warning to using it. But that's tricky too.
People often make this kind of mistake with timezones, and that's, after all, why we made permatime, so maybe it's worth thinking about one of the two above solutions (or a better one...).

No, I think permatime.com is behaving correctly. (and latest changes won't have touched this).
EST is really confusing. In the States, it means "Eastern Standard Time" and isn't used by anyone in the summer but is the same time as Central Daylight Time (hence the situation). But people use it to mean the "Eastern" timezone.
Add to the confusion the fact that Australia also has EST (sometimes abbrviated AEST.
I actually think EST shouldn't be in the "Locations" (there is one called EST5EDT which is equivalent to US/Eastern. Will look into it.
