Even with DST here we still have "winter hours" for many businesses where it doesn't make sense to be open late (10 PM in summer is still light out, 10 PM in winter, sun set 5-6 hours ago).
The golf courses are closed when it's too dark, but the offices aren't. You need to close the office a few hours before the golf course, even if your office business isn't strongly dependent on the amount of daylight.
