Hmm - I wonder have you seen this before? In Ireland, we change from BST to GMT on the 4th Sunday in October - ie: an appropriate TZ would be GMT0BST-1,M3.5.0/1,M10.4.0/1 (I'm not 100% certain that the changeover time is 1:00am; it could be 2:00). Anyway, the standard "Eire", "GB-Eire" and "Europe/Dublin" all seem to use M10.5.0 as the change-back date. Is there a newer version of these timezone files available, or a program which would generate them properly? (I'm using Linux 1.3) Thanks in advance, Colm. -- Colm Buckley | EMail: Colm.Buckley@tcd.ie Phone: (+353 1) 6082336 Computer Science Dept | WWW: http://isg.cs.tcd.ie/cbuckley/ Trinity College | finger cbuckley@isg.cs.tcd.ie for more info.
