What does System Preferences->Energy saver say in your Mac? Plus what to the logs (/Applications/Utilities/Console) say about the waking up?
Is it your own computer or a company computer?
Look into
System Preferences > Energy Saver > Schedule
Look into
System Preferences > Energy Saver > Schedule
Its my own computer
----------
The energy saver is set to Computer sleep 30 mins, and Display sleep 25 mins. and 1.Put the hard drive to sleep when possible, 2. Wake for network access, 3.Allow power button to put computer to sleep are all ticked.
I have looked in the console and there is nothing about waking up or if there is where will I find it ???

Look for a "Schedule..." button at lower right.
Click it.
What does it show?
Todays EFI updates may have addressed some of these issues, but they are well documented. See the information in my thread here:

Preventing the Mac from sleeping has helped many here. I have installed the update for ML on my Imac and rMBP but have yet to test things out. I will post back in the thread if the update has cured this.
I have not yet messed with my MP as it has a custom setup I don't want messed around with...Runs 24 / 7 as a server anyway.

Further information on the update to ML can be found on the front page article here:

I have returned the Imac to it's factory power settings ( reverse the terminal command's in the thread I posted above) and have left it to see what happens...Can't sleep, so will keep an eye on it now.

Others said it might be a known issue. But I would try to uncheck "Wake for network access" and test.
Problem Sorted
If anyone has the same problem then I found the answer from Macman45 if you cant get hold of him then here is how it was explained to me, you need to go into your Applications folder then Utilities, then Terminal, and type sudo pmset autopoweroff 0 and sudo pmset standby 0 this will sort it out for you as it worked with my mac also when you finish typing the command you will be asked for the system password this is the one you set up on your mac when you first had it.
Hope this will help anyone who is having the same problem I had. Good Luck
