FW: Daylight Saving in Western Australia

The first is the Daylight Saving Amendment Bill 2007 http://www.parliament.wa.gov.au/parliament/bills.nsf/BillProgressPopup?o penF orm&ParentUNID=713549006591B118C8257290002753CB Which calls for an early referendum to be held on 20th October, 2007 instead of 2009. The bill originates from the National Party, which are a rural party where Daylight Saving is strongly opposed. A referendum on the 20th October would mean only a week's notice if Daylight Saving gets the nod or not! The second is the Daylight Saving Amendment Bill (No.2) 2007 http://www.parliament.wa.gov.au/parliament/bills.nsf/BillProgressPopup?o penF orm&ParentUNID=EFDF9EAD189C0FBDC82572A5000E949E This bill is being done by Matt Birney, who was one of the co-sponsors of the original bill that got up in November. He wants daylight saving to end 2 months earlier for the rest of the trial, ending on the last Sunday in January instead of the last Sunday in March. He is an MP of a country seat and is trying to get a compromise to appease voters. Both bills are unlikely to get up, as the Labor Government has stated that it will not allow its members to have a free vote on the issue. The second bill looks like it wont get support from anyone even from Birney's own Liberal Party. The Nationals may support it if their own bill does not get up. The Labor Party states that both sides had a free vote last year on the issue and that Parliament in the lower and upper houses agreed on a three year trial. The Liberal Party has obviously changed their mind and will force their members to vote for the National Party amendment. It will be interesting to see if Liberal Matt Birney crosses the floor to vote with the government on his own bill that he co-sponsored! Also, as a side note, Daylight Saving looks like it may increase in New Zealand next summer, for more information check out: http://www.stuff.co.nz/stuff/4002144a7693.html Jacob

Timezones now in use
by Stuart Bishop March 27, 2007

March 27, 2007

Hi. In the pytz Python library, I provide a list of common time zones. This list can be used to generate lists of available time zones for a user to select from. I'm currently generating this list simply by taking all timezones and removing: - Those listed in the backwards file - Those that have a single path component except GMT and UTC - Those that start with Etc/ - Those that start with SystemV/ This still leaves some false positives though, such as US/Pacific-New. Is there a better way I should be generating this list? Or do I just need to blacklist irrelevant time zones as they are reported? -- Stuart Bishop <stuart(a)stuartbishop.net> http://www.stuartbishop.net/

Symlink first step: variable renaming

NewsCode=50368&NewsKind=Current%20Affairs ----------------------- Friday, March 16, 2007 - ©2005 IranMania.com LONDON, March 16 (IranMania) - Parliamentarians have prepared a double-urgency draft on daylight saving time based on which the government will be obliged to change the timings by an hour at the start of spring and autumn. According to IRNA, 37 parliamentarians presented the draft to Majlis Presiding Board. The draft referred to the successful experiences of the past and reports of Majlis Research Center about the economic advantages of changing the time at the beginning of spring and autumn. MPs have proposed that the formal time in the country be adjusted forward by an hour early spring (to start March 21) and retracted in autumn by an hour. Earlier, Energy Minister Parviz Fattah said the government is opposed to changing the time. Daylight saving time (DST) is the convention of advancing clocks so that evenings have more daylight and mornings have less. DST can save energy by substituting summer afternoon sunlight for electrical lighting. Consequently, it influences the economy and traffic accident rates. ----------------------------- Alexander Krivenyshev http://www.worldtimezone.com New York, NY

Hmm. I hurried to assert that it was hanging, it was actually searching. It seems that zdump -v algorithm is to start with minimal time_t possible (large negative number in our case) and to go to maximum time_t using 12 hours increments and doing certain checks for DST jumps. Well, with 64-bit time_t start date is somewhere 200 milliard (10^9) years ago and end date is the same in the future, so iteration over those years takes quite a while. And tz db doesn't contain anything useful for too distant years anyway. I think that zdump should be optimized to limit its search range. At the very least for the start point - what is current estimate of the age of our Universe :-) -- Andriy Gapon
