October 17th special sun rise???

Coming October 17, 2008 the sun will rise continuously for 36 hrs(1.5 days). During this time the US countries will be dark for 1.5 days.
It will convert 3 days into 2 big days. It will happen once in 2400 yrs. We're very lucky to see this.
Everybody is getting messages like this both in emails and in mobiles. Is it true? Well there is no genuine websites has confirmed. I could see this news on blogs forms.
