Ahhhh, okay thank you. I thought the timestamp was more precise in relation to when the block was mined, so that we could have the difficulty adjustment more in line with the network's mining power. I didn't think it was taken as another data you could put whatever you wanted (within a specified range)
However, I had always assumed that in bitcoin mining there existed a method of choosing the correct order of combinations, which was particularly efficient and widely used by all miners. I thought that these settings were rarely altered.
I have a Bitaxe gamma and it did not allow me for changes to that types of configurations.
