Hello, I guess this is a FAQ, but anyway here goes. As you know: ~% TZ=Australia/Brisbane date Fri Nov 16 13:18:11 EST 2001 ~% TZ=Australia/Sydney date Fri Nov 16 14:18:11 EST 2001 which is quite confusing, not to mention: ~% TZ=US/Eastern date Fri Nov 16 00:56:55 EST 2001 Since according to http://www.dstc.qut.edu.au/DST/marg/daylight-other.html#zones the correct abbreviations are AEST, AEDT, etc, but are the reasons for not updating to those unique unambiguous abbreviations. What software would break if such a change were made? Jens
