Re: License for the tzdata information

Edwin, some years ago there was talk of forming a sub-group of this mailing list to tie down the loose ends to make this data register-able. Since all tzcode is derived from public domain, the only copyrightable part of it would be it, as a collective work. I dropped out of that group very early on, due to my interest in marketing my private collection of public domain time zone data on my own. To the best of my Intellectual Property Law knowledge, tzcode is intrinsically in public domain, unless one of its contributors objects. I've been on this list for well over a decade and can't imagine anyone would. Cliff Hancuff In a message dated 4/28/2009 6:01:27 P.M.

Unfortunately I got not much info from Wikipedia, the tzdata or the tzcode files. The tzcode says "This code is in the public domain", but the tzdata doesn't have it, just a "This information is by no means authoritative". So... is there a license under which the tzdata is distributed?

24:00 versus 23:59:59--insights?
by Olson, Arthur David (NIH/NCI) [E] April 28, 2009

April 28, 2009

There are a few places with rules such as "... lastFri 0:00 ..." that should be "... lastThu 24:00 ..." One possibility is to rewrite the rules that way; doing so buys error messages from pre-1998 versions of zic. Another possibility is to rewrite the rules as "... lastThu 23:59:59 ..." which works with pre-1998 versions of zic but is a second off. A third way is to use 24:00 and, where it is used, include a comment about either upgrading zic or using the 23:59:59 dodge. I'd appreciate any insights on how to go forward. --ado

24:00 versus 23:59:59--another possibility
by Olson, Arthur David (NIH/NCI) [E] April 28, 2009

April 28, 2009

Yet another possibility is to add a special case to zic to treat instances of 23:59:59 as if they were 24:00; this lets us use 23:59:59 in input files to make pre-1998 versions of zic happy and to get correct-to-the-second results out of post-2009 versions of zic. --ado

South Australia trial successful
by Steffen Thorsen April 28, 2009

April 28, 2009

Hello, According to the official press release, South Australia's extended daylight saving period will continue with the same rules as used during the 2008-2009 summer (southern hemisphere). From http://www.safework.sa.gov.au/uploaded_files/DaylightDatesSet.pdf The extended daylight saving period that South Australia has been trialling for over the last year is now set to be ongoing. Daylight saving will continue to start on the first Sunday in October each year and finish on the first Sunday in April the following year. Industrial Relations Minister, Paul Caica, says this provides South Australia with a consistent half hour time difference with NSW, Victoria, Tasmania and the ACT for all 52 weeks of the year. ... (No changes needed to tzdata though.) We have a wrap-up here: http://www.timeanddate.com/news/time/south-australia-extends-dst.html Best regards, Steffen Thorsen - timeanddate.com

permatime.com - a way of representing times as urls (using the tz database)
by Tim Diggins April 27, 2009

April 27, 2009

Hi - just wanted to firstly, let you know of a simple web application, http://permatime.com , that we launched a while ago, which relies on the tz database info (via the ruby tzinfo library). Many thanks to the tz database maintainers (and also to ruby's tzinfo maintainers)! Also... I was wondering if anyone had any ideas if there is a public domain source for mapping city names (and single timezone countries) to timezones? We have manually added a few (including European single timezone countries and some prominent Asian cities) as aliases of timezones, but are always getting requests for a more comprehensive set of cities. kind regards Tim FYI: Permatime.com provides a way of representing times as urls, or "permatimes". Imagine you want to announce an event with participants across different time zones. Simply set the time, in your time zone, and permatime.com will generate a link for it. If you share this link with others, they will see that time in their own local time zone (and any other zones they choose). Use a permatime link to arrange a phone call, timestamp a blog post, announce a webinar...
