question about packet time stamping

I noticed that the driver maintains information about
the received packet
time (field "time" in struct hfa384x_rx_frame in
hostap_wlan.h) in respect
with the network interface.
Is this timestamp converted somewhere in the code to
refer to the host
computer local time ? I think i have seen some code
that does this but
i want to make sure.

Also is there a way to get the timestamp of the packet
when it actually
leaves the interface and goes into the air ? i.e.
something like a TX
timestamp ? Or otherwise does the prism chip generates
a TX END interrupt
as a UART does ?

I am NOT interested in the time that the packet is
passed from the driver
to the network interface because it takes some time
(due to medium access
delays) for the packet to go into the air.
