Thanks for the feature suggestion!  Please try upgrading to iPXE 
(http://ipxe.org), which already increments the "secs" field, and so should 
work correctly in your network with no modifications required.

You should upgrade to iPXE anyway, since it is actively maintained; it's just 
a happy coincidence that your particular feature request has already been 
implemented in iPXE.  :)

Also, sorry about the extended delay in responding; I have only just received 
your message.  I believe the gPXE project infrastructure (including the 
mailing lists) has been broken for over a month now.

(Redirected to the ipxe-devel at lists.ipxe.org mailing list, which works.)
