Force openvpn client to disconnect after x time

[alivdel]

hello,

i know with the Option "inactive x" openvpn will be disconnected after x seconds inactivity( idle).
i checked many Posts but all of them are about inactivity time.
but i want to know is there any Option to force openvpn Client to be disconnected after y time even if there is a traffic (not idle).
thanks.
