If a moderated message is set to automatically release after a certain number of days, this Release Time setting determines the default time at which it will be released.
For example, if you set the Release Time to 10am, and the Release Days to "the same day", then Lyris will set all moderated messages submitted to this list to automatically approve at the next time
10am occurs. If you submit a message at 11am, it will be set to automatically approve the next day at 10am. If you submit the message at 9am, it will automatically approve an hour later, at 10am.
