Discrepancy between zone.tab ordering and northamerica details
by Eric Fischer Oct. 21, 2008

Oct. 21, 2008

We just ran into a bug at work where users in US Central Time were identified as being in America/Indiana/Knox instead of in America/Chicago because code was running through the list of time zones in zone.tab looking for the first one that matched the current GMT offset and DST state, and America/Indiana/Knox is currently observing CDT and ordered before America/Chicago. I hope this is actually a use that the file ordering is intended to support, but even if it isn't, the zone.tab file seems to be misleading for some Indiana towns. In particular, northamerica says that Petersburg is Eastern and Knox is Central, but zone.tab says that Petersburg is Central and Knox is Eastern. I've attached a patch to bring zone.tab into line with northamerica, at least for these two places. Eric

FW: Uncertain usage/scope of a possibly standard timezone name 'MEZ-1MSZ'
by Olson, Arthur David (NIH/NCI) [E] Oct. 21, 2008

Oct. 21, 2008

I'm forwarding this message from Stephen A. Hellberg, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado From: Stephen A Hellberg [mailto:HELLBES@uk.ibm.com] Sent: Wednesday, September 10, 2008 8:11 To: tz(a)lecserver.nci.nih.gov Subject: Uncertain usage/scope of a possibly standard timezone name 'MEZ-1MSZ' Hello, I'm not a member of the distribution list, although I believe my enquiry is covered by its scope, and I wonder whether you might be able to circulate my enquiry (and return any replies) as my own research has failed to identify an answer. I'm trying to service a request to recognise the standard timezone name of 'MEZ-1MSZ', but I've so far not found any documentation to support or define the scope if this is an acceptable POSIX TZ value and a standard timezone name. The suggestion has been made that MSZ is a widely(?) employed alias (in some region(s) of the Gernan speaking world?) for MESZ that is standardly defined for "Mitteleuropäische Sommerzeit" (GMT+0200); MEZ being an accepted acronym for "Mitteleuropäische Zeit". And, I whilst I can find instances for the use of the standard(?) 'MEZ-1MSZ-2' I have been unsuccessful in locating any equivalence for 'MEZ-1MSZ' itself. Is MSZ equivalent and a widely accepted acronym matching MESZ, and if so where and how typical is its use? How does it differ to the 'MEZ-1MSZ-2' standard? Can you/anyone advise on the practice of employing 'MEZ-1MSZ' as a POSIX TZ value or indeed how prevalent its use is, or in which region (likely related to honouring DST somewhere in the vicinity of Berlin?) and whether this is directly equivalent to other common/standard names, such as CET-1CEST? What should its Olson equivalent be? (Whilst my inconclusive researches have been more extensive, support for the above statement appears available readily here (amongst other places): http://www.timeanddate.com/library/abbreviations/timezones/eu/cet.html http://www.timeanddate.com/library/abbreviations/timezones/eu/cest.html http://www.all-acronyms.com/special/time_zone_acronyms_and_abbreviations.asp http://de.wikipedia.org/wiki/Zeitzone ) Thank you in anticipation, Stephen --- Stephen Hellberg Java L3 Service, IBM Hursley Email: hellbes(a)uk.ibm.com ________________________________________ Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Australia/Sydney TZ DST
by Geoff Capper Oct. 20, 2008

Oct. 20, 2008

Hi, I had a browse through your site and messages searching for the reason Java had not been updated with the changed DST dates for Eastern Australia, as Java indicates that they depend on results here. I noted a request for Australian DST information, but also noted that your database hasn't included recent changes to some of the Eastern seaboard DST dates. The Australia/Sydney zone in particular changed to DST on October 5th, and in future years the change will be on the 1st Sunday in October, and will end on the first Sunday in April. I believe the southern states are also in line with this. Further details are available from the NSW AG's Community Relations Unit site: http://www.lawlink.nsw.gov.au/Lawlink/cru/ll_cru.nsf/pages/cru_daylightsavi… Kind Regards, Geoff
