[OSM-dev] Timestamp in PBF files

[marqqs at gmx.eu]

Hello,

did you know that PBF file timestamp has anniversary these days? :-)

https://wiki.openstreetmap.org/w/index.php?title=Talk:PBF_Format&diff=708490&oldid=705430

After some thought...
would it hurt if there were _two_ file timestamps in a PBF file? One string-formatted according to the definition from a year ago (see OSM Wiki on "PBF"), and a second one in UNIX time format.

osmconvert would then write _both_ of these timestamps - for reasons of compatibility.

Thus, Frederik's new PBF file timestamp could be processed even from now on.

As soon as the decision has been made, one of both file timestamp procedures could be removed from the code.
