Not an issue, but a question

Is it possible to set the time at which the alert will be displayed? What I want to do is schedule reminder alerts. Ideally, it would be possible to trigger the alerts with something like the unix program remind.

You can schedule things in OS X with a LaunchDaemon or LaunchAgent. Daemons are loaded when the computer boots and run as root. Agents are loaded when a user logs in and run as the user. They are controlled by plist files which contain keys to tell them when and what to run. So you could script your alert and then trigger it with a LaunchAgent set to run it at the appropriate time. Check out http://launched.zerowidth.com for a launchd.plist helper.

you could do it via a cron job too.
