How to use the online alarm clock

As you finish the early preparation and leave the tea room kitchen, a 2:39 am alarm can mark the moment when the morning rolls need to start baking. It gives you a clear cue before 3:00 am, without relying on a hurried glance at the clock while putting away bowls, checking trays and getting ready to head out.

Because the kitchen computer may become inactive before the baking cue, the alarm needs a little planning around how it will run. The browser alarm cannot sound after its page has been closed or the computer has gone to sleep, so the morning rolls could go into the oven late. Keeping the page open and preventing automatic sleep makes the alert more dependable; a separate alarm elsewhere is sensible if nobody will remain near the computer.

A pre-dawn baking shift usually means working with strong contrasts between a bright screen and a dim kitchen. Lowering the display brightness after setting the alarm reduces the glare while the final jobs are completed, and placing the screen away from direct sight keeps it from dominating the room. At 2:39 am, a warm work light over the preparation area can make checking ingredients and surfaces more comfortable than repeatedly looking towards a luminous display.

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 2:39 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.
