By sleep period do you mean sleep time for complete device or only for cpu's? If you want to check for device as a whole, you can see the print in the kernel log. If you want to check programmatically, suspend_devices_and_enter() is the function.

Both processor dependent and sleep level dependent.  There's a certain
amount of latency induced by the hardware waking up.

Look at /sys/devices/system/cpu/cpu*/cpuidle/state*/latency
