How to use the online alarm clock
While you are getting ready to move the car once the daytime restriction has ended, setting an alarm for 10:02 pm keeps the reminder in place before you need it. That leaves enough time to check where the keys are, confirm the permitted hours on the local sign and decide where the vehicle will go. If you intend to wait until 11:00 pm, use this alarm as an earlier prompt rather than relying on the clock catching your attention.
Because the reminder is being prepared well ahead of the move, leave the alarm running somewhere that will remain awake and audible. A browser alarm cannot sound after its page is closed or the phone or computer falls asleep, so it may fail to prompt you to move the car. Keep the page open, prevent automatic sleep until 10:02 pm, and set the volume high enough to hear from the room where you will be waiting.
Once the route and parking place are settled, there is little reason to keep looking at a bright display throughout the evening. Lower the screen brightness, switch to a warmer night setting if available, and place the phone face down while the alarm runs. At 10:02 pm, a brief glance is enough to read the alert and collect what you need without spending the remaining time before 11:00 pm staring at the screen.
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 10:02 pm?
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.
