No, you can't hunt waterfowl til dark. You can hunt til sunset, which is about 30 minutes before it gets dark. One half hour before sunrise til sunset. This of course is on private land.OnWMA's or NWR's, you must stop hunting anywhere from 12:00 to 2:00. I know of no government land that allows you to hunt til sunset.
Most WMAs in SC allow you to hunt half our before sunrise until sunset. Draw hunts you can only hunt til 11am i believe, and at one other place you cant enter until 3am and you cant stay past 11am.
