How iptables behaves on timezone change?
- by pradipta
I have doubt how iptables keep changing the info in iptables when timezone is change. I am using iptables s v 1.4.8
I have blocked one IP with following details
# date
Thu Jun 6 12:46:42 IST 2013
#iptables -A INPUT -s 10.0.3.128 -m time --datestart 2013-6-6T12:0:00 --datestop 2013-6-6T13:0:00 -j DROP
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
DROP all -- 10.0.3.128 anywhere TIME starting from 2013-06-06 12:00:00 until date 2013-06-06 13:00:00
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
But after I change the timezone following things happened automatically .
AFTER TIME ZONE CHANGE
+++++++++++++++++++++++
#date
Thu Jun 6 15:17:48 HKT 2013
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
DROP all -- 10.0.3.128 anywhere TIME starting from 2013-06-06 14:30:00 until date 2013-06-06 15:30:00
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination

The time value is changed in the rule .
It is changing with the timezone how. Where iptables keeps track of timezone.
Kindly explain me.
