Where I am at, we use Audio Vault.
Moving through the time changes are actually really simple. You delete the 2AM hour from Selector, but leave the hour header there for AV Scheduler to see, but it has no contents. Take out all the updates from 12AM - 4AM. Go to station at 12AM, change clocks to 1AM and move seamlessly through the day. Your playlist may run a little long for a few hours but catches back up later in the morning. That's where a lot of stations have problems, they forget to take out the updates and the automation gets really confused when you change the time.
For fall back, selector sneaks an extra hour of music into the 2AM hour, because Audio Vault won't accept anything but a 24 hour day, so there is 2 hours of music in 1. Take out updates again between 12AM - 4AM, go in at 1 and change the clocks back to 12.
Granted, this is the best way I can do it with Audio Vault, other automation systems have their own ways. And of course, your mileage may vary.
