[Terminator] How did the humans figure out that their enemy was Skynet, not other humans, and how long did it take?

Were there subtle signs that indicated something was interfering with combat operations that couldn't have been done by humans? Did leaders eventually talk to each other and figure out no one knows why they are fighting and everyone thinks they are purely doing self defense? Did the machines openly start attacking humans and if so, at what point did the machines decide to do so?

According to the video game Resistance it took about a year to figure things out another year or two to connect the dots to judgment day and skynet. Bout six months after judgment day rumors of killer robots were out in the survivor enclaves. By a year nearly everyone had seen an HK or terminator unit in the distance or narrowly escaped one. A year or so after that the resistance started forming to protect people and the discovery of how widespread and prepared skynet and it's machines were led to the conclusion it had started the war. Really only after John Conner had proven himself that people really believed him that skynet started the war and wasn't just some left over rogue weapons system.
