Device Events Lifetime

Hello, I am implementing the platronics hub sdk into my web application to communicate with plantronics devices. I have a case where I click a button on the docking station or headphones several times, then start listening for events via query (Spokes/DeviceServices/Events). I noticed that in response I get events that happened 1-2 seconds ago. My question is whether I am able to deduce from the response when an event happened so that I can filter them or send the SDK an event in which I tell it to clear all events before listening for them. Thank you in advance for your answer
