Is time empty of inherent existence?

My understanding of dependent origination is that it asserts that all things are empty of inherent existence. On an intellectual level I can appreciate and accept this however I struggle when it comes to time. Is time included in this? Is it dependent on something else and if so what kind of things are conditions for time? In my mental picture of the world time is kind of a backdrop for everything else but clearly this mental picture conflicts with dependent origination.
