How to use the online alarm clock
While you watch the clock for the moment to take the gritter out after a Highland snowfall, an alarm set for 3:07 am keeps the departure tied to the planned time. It is still deep night, with 4:00 am some way ahead, so the alert can separate waiting from getting the vehicle moving without repeated clock checks.
Before the gritter is due to leave, check where the browser’s sound is being sent. Connected headphones can quietly become the active output, leaving the alarm audible only through earpieces that are sitting on a desk or inside a coat pocket. A brief sound check confirms that the alert will come from the intended speaker and at a useful volume. If the browser has stopped running or the computer has fallen asleep, the gritter alarm will not sound, so use a separate alarm when missing the departure would hold up the work.
A 3:07 am start can carry noise through a house that is otherwise silent. Keep keys, boots and outdoor clothing together near the exit, close internal doors gently, and set the alert only as loud as needed from your chosen speaker. That reduces searching and movement near sleeping people when it is time to head into the snowy Highland night.
Common questions
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.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 3:07 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.
