The way it is supposed to work (or so I think): The current update time, minus the last update time, should not exceed the heartbeat time. This translates to: if you want to update once a day, on exactly the same time each day, you need to set heartbeat to 25 * 3600 = 90000. Why 25 hours? Because of daylight saving.
