Hi MrWill,
You might take a look at this tutorial to see if there may have been something simple that was just overlooked.
Time Zone
If not, then run a "sfc /scannow" (no quotes) command to see if it can find and fix any system file errors that may be causing this. You can see how below.
System Files - SFC Command
Hope this helps you,
