Cron - don't shut down if the server was just started

In `awscron`, we check every minute to see if there were recent sign-ins, but we don't check if the server was just turned on, so the server would just turn off within a minute of being turned on if you didn't log in

Start by locating the awscron logic that checks for recent sign-ins every minute. Verify how it detects when the server was started, then ensure a newly started server is not shut down solely because no sign-in occurred. Done means a server remains running after startup without a login while the existing shutdown behavior still works.
