Linux下的时区问题

刚才被Linux的时区搞得晕头转向，记录如下：
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

这样就把时区变为了上海时间

把时区变为UTC：
ln -sf /usr/share/zoneinfo/UTC /etc/localtime

另外还有IP route，也很搞：
root@A7570_SH15_A:~# ip rule
0: from all lookup local
32764: from all fwmark 2 lookup sctp2
32765: from all fwmark 1 lookup sctp1
32766: from all lookup main
32767: from all lookup 253
root@A7570_SH15_A:~# ip route list table sctp1
default via 192.168.29.254 dev eth4
root@A7570_SH15_A:~# ip route list table sctp2
default via 192.168.30.254 dev eth5
root@A7570_SH15_A:~# iptables -L -t mangle
