Web alarm clock for 3:35 a.m.
You are preparing the fish farm’s backup generator at 3:35 am, before a power interruption makes it necessary. Set the alarm while you check the fuel level, starter, cables, and the path to the generator shed. The remaining 25 minutes leave room to finish those checks before 4:00 am without rushing through equipment you may need in the dark.
Your generator preparation depends on hearing the alarm at the right moment, so keep this page open and the phone awake after setting 3:35 am. If you close the page or browser, or let the phone sleep, the browser alarm may not sound and the generator start could be delayed. Turn the volume up enough to hear it near pumps or aerators, then confirm that the displayed alarm time uses am.
Moving between fish ponds and the generator area before dawn can mean looking from a bright phone into very low light. Keep the screen dim enough to read the alarm without lighting your whole field of view, and avoid staring at it while walking on wet paths. At 3:35 am, place the phone where the alarm remains audible but its glow does not reflect across the water or interfere with seeing switches and labels.
