ISC DHCP / system time change

[Stephens, Bill {PBSG}]

It doesn't.  The client is responsible for renewing it's lease before it
expires.  The client has no way of knowing you set the clock forward on the
server.  One reason the server doesn't control the client is so the server
doesn't expend excessive cycles trying to contact machines that are no
longer on the network.  Envision a system with a couple of thousand systems
on the network and a single server trying to proactively keep them updated
with time and lease information.  You'd quickly run out of system resources
and saturate your network.

Hi,
   I have one question. DHCP server is working fine and gives some leases to
some clients. At that time if I change the system time of server, it seems
to the server that some leases expire though that are used by some clients.
How DHCP handles this situation ?

With best regards,
Sahoo
