Import the planet into your database. 3. Run Osmosis "setup replication interval" task to create a workdir. 4. Look through planet.osm.org to find a minute or hourly replicate state file that has a timestamp a few hours before the day of your planet file. 5. Download the state file into your workdir from step 3. Rename it to "state.txt" 6. Start the replication task and wait for your database to catch up. The state.txt file will contain a timestamp representing the freshness of your database. Osmosis (and osm2pgsql I'm sure) will not clobber existing data if it's already there. > Is it possible to get the timestamp of the planet file in any compressed > format without decompressing? Look at the file name.
