[OSM-dev] Little doubt about planet updates

[Juan Lucas Domínguez Rubio]

Hello, I have downloaded this file:

http://planet.openstreetmap.org/planet-110119.osm.bz2

which according to [1] contains all data in the OSM DB as of:

19.01.201 01.00 AM UTC
(UK time = UTC)

My intention is to apply daily updates to it. According to this timestamp.txt file [2], a file called:

http://planet.openstreetmap.org/daily/[date]-[date+1day].osc.gz

contains the changes performed during the [date] day (UTC time), therefore the first file I should use in my case would be:

http://planet.openstreetmap.org/daily/20110119-20110120.osc.gz

Is this ok?
Am I missing something?

What happens then with changes done between 19.01.2011 00.00 and 19.01.2011 01.00?
They will be applied but they were already there.
So I presume applying changes a second time is not a problem?


Regards,
Juan Lucas
