As for your boyfriend, it's well easy to get him to sleep at a normal time. Assuming he's willing, you just have to correct his body clock. Make him get up at the same time as you after he's gone to bed at his usual time. Then make him stay awake ALL DAY, no naps, no nothing, all the way until his normal bedtime again. Then make him get up at your time again. Eventually he'll get tired at the same time as you. People don't necessarily have preset hours they HAVE to sleep, it's all down to your lifestyle and habits and it can be corrected. He has to go without a lot of sleep for a few days, but it can be solved, just like jetlag.
I heard another method is more effective: To go to bed later each night until you come full circle. The problem with going to bed earlier is the body is not ready to go to sleep, so getting tucked in bed will not help. it can help with jet lang but not a serious body clock issue. Sometimes you can change conditional factors i.e. food/exercise but If all al fails this method is meant to be quite good. that is if the sleep disorder is a late body clock.
