Work on System/360 started in 1961 (and in some sense two years earlier, but let's not get into that). System/360 and OS/360 were announced in April 1964. The Dartmouth Time Sharing System first became operational in early 1964 and wasn't available for use until after System/360 and OS/360 had been announced and already had years of development.
