这两天受FortiGate启发，试了下iptables的时间控制规则，整理如下：
1、每天固定时间段匹配
iptables -I FORWARD -s 172.17.1.132 -d 192.168.1.119 -m time --timestart 09:40 --timestop 09:59 -j DROP
2、按周固定时间段匹配
iptables -I FORWARD -s 172.17.1.132 -d 192.168.1.119 -m time --timestart 09:40 --timestop 09:59 --weekdays Wed,Thu -j DROP
3、按固定日期匹配，注这里比较特殊，可以看见下面的时间是17点不是9点，是因为时区的原因，要差8小时。
iptables -I FORWARD -s 172.17.1.132 -d 192.168.1.119 -m time --datestart 2014-3-19T17:40:08 --datestop 2014-3-19T17:59:50 -j DROP
附上帮助说明：
time match options: --datestart time Start and stop time, to be given in ISO 8601 --datestop time (YYYY[-MM[-DD[Thh[:mm[:ss]]]]]) --timestart time Start and stop daytime (hh:mm[:ss]) --timestop time (between 00:00:00 and 23:59:59)[!] --monthdays value List of days on which to match, separated by comma (Possible days: 1 to 31; defaults to all)[!] --weekdays value List of weekdays on which to match, sep. by comma (Possible days: Mon,Tue,Wed,Thu,Fri,Sat,Sun or 1 to 7 Defaults to all weekdays.) --localtz/--utc Time is interpreted as UTC/local time
