We can see how long the AP has been up and connected since the last reboot, but we don't have an overall age of the device measure per say. The first part of the serial number of the device does correspond with the release date, if you send me the serial number of the device in question I can give you an estimate of when the device was first released? My email address is communityhelp@aerohive.com in case you'd like to send that to me directly.
