OK... I knew there was probably already a way of doing this :-).

Can osmfilter also randomise time data for you? I currently run the following
script but it would be nice to use a more common method.

#! /usr/bin/perl
$time = (time()-(2**21)) + int(rand()*2**22);
while (<>) { @t = gmtime($time);
  $o = sprintf '%4d-%02d-%02dT%02d:%02d:%02dZ', 1900+$t[5],
     $t[4], $t[3], $t[2], $t[1], $t[0];
  s/<time>\d{4}-\d\d-\d\dT\d\d:\d\d:\d\dZ<\/time>/<time>$o<\/time>/g;
  print; $time += int(rand()*15)+1;
}

Thanks!
