Hi, I've found an interesting issue. If I compile zdump directly from the tzcode package (any version), it works perfectly. However, if exactly the same source is built within the full glibc tree, that one reports invalid time zone abbreviations. I have no idea whether it's a tzcode or a glibc bug. Please read the full detailed description here: http://sources.redhat.com/bugzilla/show_bug.cgi?id=1140 and please, if possible, also report your comments to this bugzilla, so that I hope you and the glibc team can quickly catch and fix the bug together. Thanks, Egmont
