var expDays = 1; // number of days the cookie should last
var expDate = new Date();
expDate.setTime(expDate.getTime() + (24 * 10 * 60 * 1000 * expDays));

How can I set this to expire after 1 hour?

I don't know the first thing about writing cookies, but try this page: http://www.comptechdoc.org/independent/web/cgi/javamanual/javacookie.html

To begin with there is an error in the code you posted. It should be:
var expDays = 1; // number of days the cookie should last
var expDate = new Date();
expDate.setTime(expDate.getTime() + (24 * 60 * 60 * 1000 * expDays));This sets a cookie to expire after 1 day.

If you want it to expire in 1 hour, all you need is:

var expDate = new Date();
expDate.setTime(expDate.getTime() + (60 * 60 * 1000));
60 minutes in an hour, 60 seconds in a minute and 1000 milliseconds in a second so 60*60*1000 = one hour
