From 0be0174259a3a35313fe1a0413630b919f910f5b Mon Sep 17 00:00:00 2001

Subject: [PATCH] time: fix parsing of tzdata files where off_t is 64-bit
lseek takes off_t as the offset type, but gcc will normally pass a
32-bit value unless the number is wider than 16 bits. so we force
gcc to pass the constant as off_t type always by casting the constant
to off_t.
