How to use the online alarm clock
As you hand the allotment greenhouse frost check to the next person, set the alarm for 2:44 am and make clear which panes, vents and tender plants need attention. That gives them a definite handover point before 3:00 am, rather than leaving the change of shift tied to a vague instruction such as “sometime before three”.
The greenhouse check depends on the alarm surviving the quiet period after the handover. A computer or phone may enter sleep mode before 2:44 am, and this browser alarm may then fail to sound, leaving the greenhouse frost check uncovered. Keep the alarm running on an awake, powered device with the sound audible; if the person taking over cannot do that, arrange a separate alarm they can rely on away from the browser.
Whoever is travelling to the allotment should allow for the whole night journey, not only the short drive suggested by empty roads. At 2:44 am, roadworks, diversions, locked site gates and the walk from a dark parking area can add several minutes. Work backwards from the time the greenhouse must be inspected, include those final steps, and use a torch before leaving the vehicle so the route from gate to plot is straightforward.
Common questions
What happens if my laptop goes to sleep before 2:44 am?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
