When was Scripture inspired?

Since God apparently didn't deem it newsworthy to include in His Word, it's irrelevant, but it crossed my mind recently...

I find some of my best inspiration for blog posts and other ideas occurs as I drift off to sleep, when I awake in the middle of the night or just as I awake in the morning. So much so that I'm often caught in a dilemma of determining whether attempting to clock more minutes of shut eye outweighs the benefits of capturing the thoughts my mind is generating at the time. Which, one evening or early morning in the past few days led me to contemplate...

I wonder when God inspired the authors of Scripture to record His Words?
