From a738c3be31637872c622953fe749e10e295a9cd4 Mon Sep 17 00:00:00 2001 From: Jens Arnold Date: Fri, 10 Mar 2006 19:17:01 +0000 Subject: Iriver firmware compatibility kludge: RTC year offset. The offset is chosen in a way to make leap years work correctly in rockbox; the original firmware will still be one year off but doesn't reset the date anymore.
