What is the time frame for the search volume on a Keyword?

Let's say I search for AP automation and the search volume comes back as 210, where did that number come from? Is this how many searches by day, by week, year to date, etc.?

The Google AdWords tool uses monthly figures. Note that the number is averaged over the previous 12 months, so it's not very useful for seeing seasonal variations. You'd need to use Google Trends for that.
