I'm afraid it's too late for that one. The abbreviation ChST was originally suggested by Congressman Robert A. Underwood, author of US Public Law 106-564, which established Chamorro Standard Time. It's relatively common practice now to use "ChST" in local time abbreviations. For example, see: http://www.prh.noaa.gov/guam/help/tcInfo.php http://chamorrobible.org/announcements.htm I'd also say, though, that "GST" is still quite popular -- perhaps even more so than "ChST" is. It's a bit hard for this outsider to tell what's really going on there. But if "GST" is significantly more popular perhaps we should revert to it. However, my impression is that the vast majority of people in Guam don't care about this issue; the main Guam-based web sites I checked (http://ns.gov.gu/, http://www.visitguam.org/, http://www.guampdn.com/, http://www.guam-online.com/) don't seem to bother to mention their time zone under any name.

I assume these are the solar zones only. These files are pretty much obsolete now. I see that all the other abbreviations are 6 bytes or less, and use the POSIX charset, so we're POSIX compliant except for the solar zones.
