I've created a function in site.inc.php and hooked it to 'daily' to be run once a day. It sends an email summary of new subscriptions for the day. The problem is, I'm receiving two every day, one at 00:00:02 and then another at 01:00:02 then it's fine until the next day. Is there a known issue with the 'daily' cron hook? I'm running 3.0.8PRO on gentoo linux with PHP 4.4.4
SOLVED: Daily cron bug? I figured it out. My database server was running a few minutes slower than my web server. Apparently $db->save_cron_time() saves a timestamp relative to the database, not the web server. If the machines are not in sync, you'll get strange results. I wish I had access to the $db functions, I might have figured this out sooner.
