Infinity loop with dates comparison

[Suliman via Digitalmars-d-learn]

The code look very trivial, but I am getting infinity loop like:
2014-Aug-02
2014-Aug-02
2014-Aug-02
...
2014-Aug-02

Date startDate = Date.fromISOExtString("2014-08-01");

Date currentDate =  to!(Date)(Clock.currTime()-1.days); //because 
current day is not finished

        writeln(startDate);
        writeln(currentDate);

        Date nextday;

        while (nextday < currentDate)
        {
                nextday = startDate + 1.days;
                writeln(nextday);
        }
