Ah... I've been looking for a copy of that for years


My copy is one of my most valued books and as such I protect it with dear life. You would be welcome to borrow it at some point in the future but at the moment you couldn't find a crow bar big enough to prise it away from me :P

Guys,

I've now added a Sunrise/Sunset/Twilight calculator here;

webtreatz.com/component/option,com_wrapper/Itemid,84/

Once again feedback would be appreciated.

This time I made some changes;
The page state is preserved between submissions;
The default start date is today's date and the default end date is today + 7 days;
Please tell me if the captcha without the background is more readable;

Thanks for helping me test this.

PS: Before you mention it, the determination of your location is based upon your IP address and so is very hit and miss. It should get your country right and I'd be interested to hear how good it is at guessing your city too please

Regards and Clear Skies,

Dave.

Hi Dave,

The text is much easier to read. It is guessing my location correctly but I'll try the 3G connection later and see if it works.

That will be interesting. I would expect the location it gives will be the location of the base station of your service provider.
