How to use the online alarm clock
Break away from the lock-side work at 6:01 am so the bridge is ready to lift when the barge reaches the canal crossing. You may be halfway through checks or handling another task, so use the alarm as the point to stop, secure what you are doing and move into position. That still leaves a useful stretch before 7:00 am if the vessel’s arrival is not immediate.
Set 6:01 am while the bridge-lifting job is clearly in mind, then confirm that the alarm can be heard over machinery and activity beside the water. Silent mode may suppress the sound, so test the volume with enough time to change the setting. If the browser is ended or the phone falls asleep, this alarm may not recall you to the barge; keep the page active and the phone awake until it sounds.
Reaching the canal early can involve quiet lanes, towpath entrances and access roads that take longer than their distance suggests. Allow for locked gates, a walk from the parking place and any diversion around the bridge approach. Roads are often quieter around this hour, but darkness and unfamiliar turnings can slow the final part of the journey, so base your departure on the whole route rather than the driving time alone.
Common questions
What happens if my laptop goes to sleep before 6:01 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.
