In a computer, loss (or failure to retain) settings like these are caused by a faulty CMOS battery. I haven't taken apart my DS yet (cannot find my tri-wing screwdriver), but I haven't found evidence of one in the DS. So I would say these are the most likely causes:
1) DS uses a solid-state chip (requiring no power) to hold data, and that chip is defective, or
2) The battery that supplies power to hold the data is defective, whether it's a button cell, built-in, or the easily-replaced Li-Ion.
If this is a brand-new DS, try charging the battery for a while first. if it's an older one that you've had and used before and this problem only recently surfaced, I would try replacing the battery first (borrow a friend's), and if that doesn't work, the unit may need to be serviced by a professional. Keep your ear to the ground, and hopefully someone who actually knows a fair bit about DS repair may have better advice for you!
