global class MyScheduler implements Schedulable{
    global void execute(SchedulableContext SC){
        CallOut.doCallout();
    }
}

public class CallOut{
    @future(callout=true)
    public static void doCallout(){
               HttpRequest req = new HttpRequest();
        HttpResponse res = new HttpResponse();
        Http http = new Http();
        req.setEndpoint(endPoint);
        req.setMethod('POST');
        req.setCompressed(false);
        req.setBody('');
        req.setHeader('Content-Type', 'application/x-www-form-urlencoded');
        res = http.send(req);
        // do something with res.
        }
}
