Online alarm clock for 4:49 am
Wrap up your preparation and head out so the 4:49 am alarm marks the moment to begin unloading containers at Lyttelton Port. The eleven minutes before 5:00 am leave room to put away paperwork, collect your gear and reach the working area without treating the alarm as an early warning.
Because your phone may be left untouched while you finish the shift setup, check that its screen settings will not put it to sleep before 4:49 am. Keep this browser alarm visible and the phone awake, with the volume set clearly above the surrounding sound. A browser alarm cannot sound once its page has been dismissed or the phone has fallen asleep, so the container unloading could begin without your alert. For something you cannot afford to miss, add a separate alarm in the phone’s clock app.
As activity builds near 5:00 am, engines, reversing signals and metal movement can replace the quieter sounds of the night quite suddenly. Keep the phone close enough to hear at 4:49 am rather than leaving it inside a bag, vehicle cab or locker. Vibration can provide a useful second cue, especially if you are already walking towards the wharf when the alarm sounds.
