Daylight Savings Doesn't Work

Does anyone know a way to get OmniPlan (either version 3 or version 4) to correctly handle the change between standard time and daylight savings time?

I’m using a 24/7 schedule and would like to make a series of one-hour tasks to fill the day, each starting on the hour. But, I can’t make it work in either v3 or v4.

The behavior is different between v3 and v4, but neither is correct.

On most days of the year, there would be 24 one-hour tasks. In the spring, there would be one day with 23 one-hour tasks. And, in the fall, there would be one day with 25 one-hour tasks.

My every attempt has failed.
