Now()

Time ns3::Now

(

)

create an ns3::Time instance which contains the current simulation time.

This is really a shortcut for the ns3::Simulator::Now method. It is typically used as shown below to schedule an event which expires at the absolute time "2 seconds":

Simulator::Schedule (Seconds (2.0) - Now (), &my_function);

Returns

The current simulation time.
