Subject: [PATCH] Display object Last Modified times in the local timezone

Render Last Modified using time.Local and a stable timestamp format so
operators can set TZ (for example Europe/Berlin) and see wall-clock times
instead of always UTC. Embed time/tzdata and install tzdata in the image
so timezone data is available in minimal container environments.
