I bought a Timex Expedition North Titanium Automatic a few months ago and have been enjoying it, but it gains about 10s a day that I have to correct. Nowadays we have incredibly accurate and precise clocks that can tell us exactly what time it is, but all mechanical clocks and watches have some amount of inaccuracy.

How did people account for inaccurate clocks in the past? Even if time didn't need to be standardized outside of a community until the railroads and a central clock in town could act as a reference for the entire community, wouldn't the central community clock drift? Eventually the central clock could say it was midnight at sunset. While people can tell that is incorrect, how could they say to what extent it was incorrect?

I’ve completely eliminated the alarm clock from my morning routine for about six months. The biggest impacts it's had on my life are:

1. I’ve become a morning person.
2. I wake up feeling great and feel less sleepy during the day.

Becoming a morning person is a necessary side effect of not using an alarm clock because it requires the body to naturally wake up early enough for work, school, or other regular obligations. Although I’ve historically enjoyed staying up late, the brutal truth is that all humans require a certain amount of sleep, and this can't be consistently fought without an alarm clock.

The best part about eliminating alarm clocks from my life is how it has affected my day. It’s not a hidden secret that good sleep habits translate to:

1. Better mood
2. Increased energy levels
3. Clearer mind
4. Improved overall health

I can confidently say I really do feel all these benefits. In the end, it's not to any real surprise. The alarm clock interupts one of the most important cycles of your body, and so it only makes sense to leave sleep alone so it can do what it needs to do.

How I Transitioned to Natural Sleep

Once I decided to try this experiment, I created a simple plan to implement it. Before this life change, my sleep schedule was from around 1 am to 8 am. So, the first thing I did was set an alarm for the target time I wanted to naturally wake up, in my case, 7 am.

The first night resulted in 6 hours of sleep (1 am to 7 am). My body needs more than that, so by the time 11 pm rolled around, I was ready to fall asleep. It was initially tough to sleep earlier than normal, as I felt there was still time to do things, but I let my body dictate my actions and went to bed without an alarm.

That night, I slept for about 9 hours due to sleep debt. I missed my 7 am target, but it wasn’t a big deal. After that, with my body reset, I simply aimed to continue to sleep around 11 pm, meaning I was in bed by 10:30 pm. The pressure of needing to naturally wake up before work was enough motivation to forgo the later hours of the night and continue heading to bed early.

Now, I’ve settled into a great rhythm of going to bed around 10-10:30 pm and waking up around 6:30 am. What’s great is discovering how much sleep my body naturally needs (8-8.5 hours). No more trying to "hack" my body with things like miserable polyphasic sleep experiments. I know what my body needs, I succumb to it, and I’m rewarded the next day.

Some Caveats

What worked for me won’t necessarily work for everyone. Each person and their situation is unique, so results will obviously vary. Some unique factors for me are:

• I’ve always been able to fall asleep quickly, which might be due to consistent sleep deprivation, regular exercise, or both.
• My only dependent is a dog, and she doesn’t mind sleeping in a bit in the morning.
• I always sleep with white noise, which helps block out sounds that would normally wake me up during the night.
• My work schedule is consistently 9 am to 5 pm.

One final note: I still use alarm clocks for special occasions, such as early morning flights. Although I could probably wake up naturally for them, without an alarm set, I would probably wake up in the middle of the night stressed about the possibility of missing my flight.

Try It Out

This change has been significant enough in my life that I frequently recommend it to friends. I now honestly believe that the alarm clock is the single worst thing the wider population willingly inflicts on themselves. If you’re willing to eliminate the morning alarm clock from your life, I would love to hear how it goes. Good luck!

While pondering an off-grid microcontroller project, I got to wondering: A light sensor can obviously detect day vs night. So it could be used as a very cheap way to set a device's clock - but how accurately? To within an hour? A few minutes? How would you do it?

Questions that arose from this include:

• Should it detect dawn/dusk (light <-> dark transition), or noon/midnight (brighest/darkest time) ?
• How do dawn/dusk times relate to clock time? Does it depend on lat/long?
• If using dawn/dusk, what light level threshold to use?
• The same threshold for dawn & dusk, or different ones?
• Better to detect a darker threshold (start of dawn, end of dusk) or a lighter one?
• Some days will be lighter/darker than others, so how to manage averaging of times?
• How accurate could it be made?

My naïve first stab at this would be: Pick a light threshold. Record the dawn/dusk times according to that threshold. Average them, call that "noon", and gradually tweak the clock time over several days to bring it into line with the sensed/calculated "noon" - but a searching for graphs of sunrise/sunset times quickly showed that the midpoint of sunrise & sunset is not noon.

Googling threw up lots of results for sensor lights combining a clock and a photocell, but I couldn't find anything about using the photocell to set the clock. So does anyone know if this has been tried before? Is it a non-starter for some reason?

Edit:

Perhaps it's worth sharing the project I had in mind, which is a rain alarm so I can rush out and get the washing in from the line when it starts to rain. I was thinking how annoying it would be if I left it switched on and it rained in the middle of the night and the alarm woke me up. So I decided should automatically avoid triggering during the sleeping hours of night (say 10pm to 8am). My first thought was a photocell so it wouldn't trigger when it's dark. Then I remembered that it gets light at 3am at the moment, which wouldn't work. So it needs a clock. How to set the clock:

• Manually - Needs a user interface with buttons and a display. Seems overkill just for a clock.
• Serial port - Clunky to plug a laptop in just to set the clock.
• WiFi - Needs a username and password or WPS, and an ESP32 or similar - again seems overkill just to get the time.
• GPS - also overkill and expensive.

I've been rewatching Ozark. The third season features a bipolar character, and his storyline has been hitting me hard.
There is an emphasis on "getting better". Staying somewhere and getting better. Giving things time.
It's been making me wonder if time really makes things better.

Time heals wounds, but it doesn't fix broken things. It helps with grief. It helps forget the things that make it worse.

Twelve years ago, things got bad enough in my life that I attempted suicide. I had no psychological safety nets at the time. No mental security. What saved me at the time was a mix of luck, a couple of smart decisions on my part, and the good will of some people I barely knew.

I have since spent a lot of time creating and nurturing safety nets to make sure this never happens again. A variety of social, technological and mental mechanisms to stop me at every step, should things ever get this bad again.

And now, I'm... alive. Things got bad this last month. Really bad. Worse than twelve years ago. Worse than they've ever been. But I'm alive. My safety nets worked. I wouldn't be writing this without them.

I'm getting the feeling that I'm going to carry this burden for the rest of my life. Time didn't fix shit. I just got better at defending myself since.
