Watch out, though, as "direct date math" can really screw ya over when it Daylight Savings changes (if you're not in a daylight savings area, you're okay.) Best bet is to use getdate() to build up the array, modify the array elements, then mktime it. If you just add seconds you'll get odd results when traversing daylight savings.
