+From f3964e0fa19e0c33470f37014ebcebf0b4253363 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] sar: make buffers that hold timestamps bigger
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On systems that use Korean UTF-8 locale sar will not print timestamp
+because there is not enough space in the buffer.
+
+I bumped buffer size to 64 bytes because I figured out that 32 bytes is
+still not enough to print out timestamp when using some glibc supported
+locales.
+
+$ LC_TIME=ko_KR.UTF-8 ./sar 1 1
