-+ This is a module which is used for time matching

-+ License (GPL). Copies of the GPL can be obtained from: ftp://prep.ai.mit.edu/pub/gnu/GPL
-+ 2001-05-04 Fabrice MARIE <fabrice@netfilter.org> : initial development.
-+ 2001-21-05 Fabrice MARIE <fabrice@netfilter.org> : bug fix in the match code,
-+ thanks to "Zeng Yu" <zengy@capitel.com.cn> for bug report.
-+ 2001-26-09 Fabrice MARIE <fabrice@netfilter.org> : force the match to be in LOCAL_IN or PRE_ROUTING only.
-+ 2001-30-11 Fabrice : added the possibility to use the match in FORWARD/OUTPUT with a little hack,
-+ added Nguyen Dang Phuoc Dong <dongnd@tlnet.com.vn> patch to support timezones.
-+ 2004-05-02 Fabrice : added support for date matching, from an idea of Fabien COELHO.
