[PATCH RFC 06/12] time: Fix build warnings for time64_t to __kernel_time_t warning on 64-bit systems.

[pang.xunlei]

The kernel uses 32-bit signed value(time_t) for seconds since 1970-01-01:00:00:00, so it
will overflow at 2038-01-19 03:14:08 on 32-bit systems. We call this "2038 safety" issue.

This patch fixed the build warnings brought by former patches.
