Set cookies expire on the next day at 0.

This information on the Internet is very rare, try to csdn one of the methods to calculate the time, the return is invalid date, do not know whether the different versions of the IE version returned results are different

Find another very simple way to get back. After a day, set the number of seconds to 0, the code is as follows

function (n) {var ctuskytime=New  Date (); Ctuskytime.setdate (Ctuskytime.getdate ()+1) ; Ctuskytime.sethours (0); Ctuskytime.setminutes (0); Ctuskytime.setseconds (0); Document.cookie= "ctuskytime_cookie;expires=" +ctuskytime.togmtstring ();}

Really good!
