Our sump pump runs constantly, but only at night. Why?

Our basement has a new sump pump (less than six months old). Has a battery back up. Stainless steel sump.
The pump cycles constantly starting at about dusk, and keeps going (at least until we fall asleep). There's very little water in the sump. No more than there is during the day. During the day it doesn't run.
The plumber who installed it is coming, but he's coming during the day, and I'm afraid he's going to think I'm nuts. Can anyone think of a reason why the time of day matters?
