From 2cdc55751c33829f00510e0104562d0f8d8a9b85 Mon Sep 17 00:00:00 2001 From: Kaihui Luo Date: Mon, 22 Sep 2008 19:02:36 -0700 Subject: [PATCH] netfilter: xt_time gives a wrong monthday in a leap year The function localtime_3 in xt_time.c gives a wrong monthday in a leap year after 28th 2. calculating monthday should use the array days_since_leapyear[] not days_since_year[] in a leap year.
