Thanks for the additional information. It is helpful.
You have the option of reporting the behavior to the council in your area. Before doing so, I'd try and document the behavior by video taping the clock on your computer and letting it record the dog's barking behavior. If you have a few instances on tape and then keep a written log of the nuisance barking, you should have a valid complaint to the council.
You might also get a sonic anti bark device. It uses noise that is inaudible to the human ear to distract the dogs when they bark. This is usually effective for a little while. The problem is that the dog will get used to the noise and start ignoring it. See one such device here:
You might also offer to purchase citronella spray anti bark collars for the dogs in question. These would need to be on the dogs to be effective.
Since they are not your dogs, there really isn't much else you can do beyond what I mentioned. You might think about sound proofing your bedroom if the council and the devices don't help the situation.
