When doing some cleanup of my Modr8 module, I wanted to define a new build_mode for use by http://api.drupal.org/api/function/node_build_content/6 I realized that we don't have any standard for picking new int constants for this case in specific, or more generally. So, here's a suggested standard that I think is nearly fool-proof: When defining an additional build mode constant (or similar constant) in a contributed module, the suggested standard is to use the unix timestamp of when you write the code to minimize the likelihood of two modules using the same value. I think it's sane and nearly perfect since a new module will then never pick the same value as an existing module, and in general it's very unlikely that 2 people will by writing a new constant the same second. Am I missing anything? Any reason not to suggest this as a standard? -Peter PS - a couple easy ways to get the timestamp on you command line: date -j "+%s" php -r 'echo time() ."\n";'
