I used to do this, as a software engineer straddle 2 departmental areas, and I was explaining it to someone on Twitter last night,, in regards to my sleep schedule. I used to go in right before lunch to avoid the impromptu meetings associated with people coming back into the office. Coming in 11am-1PM allowed me to block off my productive time and work until dinner sometime between 6-8pm; and then come back to problem solving after dinner. This gave me one 6-8 hour stretch of time with little distraction vs a 3 and 4 hour stretch with lots of distractions in the first period.
