Daylight savings time is considered in your ph360 program but you won't see a change in your power hour. The power hour does not change because we force our body to adapt to daylight savings (a short jetlag feeling and we're ok again), we therefore adapt the body to the clock. So a power hour that is 10 am wouldn't change to 11am but it remains at 10 am. And we adapt the body accordingly with shifting our sleep wake cycle. Our bodies adjust to the clock, so ph360 sticks to the clock.
