The Y2K7 problem
Right, that "Y2K7" is not a typo. It "refers to the Year 2007 problem, caused by a US-mandated change to Daylight Saving Time" ( wikipedia ). From this year the US (and Canada) changed the dates on when daylight saving time is active. DST now starts three weeks earlier, and ends one week later. This causes quite a lot of problems with software that hard coded those rules. On Linux (and other Unix-like operating systems) this can be remedied by updating the zoneinfo information - check your Operating System's documentation on how to do that.
PHP before PHP 5.1.0 relies on the Operating System to provide time zone information, while PHP versions 5.1.0 and higher come with a bundled time zone database. The database that ships with PHP 5.1.0 already covers the changes in the US and Canada, however, the US and Canada are not the only places changing rules. Many places on earth change those rules all the time which means PHP's database needs to be updated as well.
Every PHP version comes with the latest release of the time zone database at the moment PHP is released. However, it is also possible to just update this data by installing the PECL extension timezonedb . This extension is released whenever a new version of the Olson database becomes available. The current version is 2007c (2007.3).

Hey Derick, That does seem to be a problem, but I wonder how many sites/systems will be affected.
Its a lesson us brazilians have already been through, because over here we have no specific date for begining or end of the daylight savings time. And this year we had a real mess because only half (or less) of the states actually "accepted" the change, so we had an internal timezone going. Real mess as you can see.
Well great post, interesting stuff, will you be here for this year's PHP Conf?
Greetz!
Life Line
I've finished reading This Way Up. It's about maps, that went wrong.
It's a good read, but htyerr were several chapters that were written in a novel way (as a video transcript, a series of letters), and I found distracting from the a tail content. It'll have worked better in a produced video.
No mention of @openstreetmap though :-(

The Early Cormorant Catches the Eel
Sorry, not the best photo! But I caught this Cormorant catching this large eel when looking for Bank Swallows, right next to Eel Pie Island in the Thames.

Updated an estate_agent office
I went to my nieces' birthday party yesterday.
The theme was pink, and that included all the food, mostly died with beet root.
Shock and horror this morning when doing number two. Not only was my turd dark red, it was also glittering at me. Apparently the carrot cake had edible glitter...
So now I know what's worse than glitter.

I've been spending some time in random London local nature reserves.
Sitting and listening, and in fifteen minutes you spot countless species.
This one was in Ham Lands Local Nature Reserve near Teddington.
