I found the date feature (for example, May 22, 2018 8:53 PM) quite nice, but the names of the time zones for Brazil are pretty much wrong. It lists:
The official names are actually
Fernando de Noronha Time
While the first and fourth are okay, I do not know which one is East and which is West (ok, if you look at a map it is obvious, but it is not the kind of thing I have in my head).
Looking at the files of my Linux system, the naming seems to be the same. I suppose the low-level naming is kept a mess for compatibility issues, but since I usually do not see this kind of stuff in websites, maybe there is some UI fix to show the user proper names?
