Either that functionality is already present as a setting or configuration option in shiichan or it isn't. If you find the setting in the administration interface, enable it, otherwise you'll have to write it yourself. If you want to do it client-side, serve some javascript that gets the local time offset and rewrites the date/time fields, but this will not work for clients that have enough sense to browse with remote code execution disabled. If you want to do it server-side, find a geoip library and serve adjusted local times directly in the html, but this will trash a naive caching setup.
