Both the Vulkan GOOGLE_display_timing extension and X11 Present
extension offer the ability to specify the desired display time in
seconds.

Similarly, I'd suggest that the min/max display refresh rate values be
advertised as time between frames rather than frames per second.

I'd also encourage using a single unit for all of these values,
preferably nanoseconds. Absolute times should all be referenced to
CLOCK_MONOTONIC.
