Disk Clock returns to the OS X Dashboard

Disk Clock version 2 is now available for the OS X Dashboard.

Disk Clock returns to the platform of it’s birth. While Apple seems to have lost interest in providing a marketplace for Dashboard widgets, Macs are more popular then ever, and Dashboard still comes with every one. Throw away that crummy, confusing 12-hour clock, and use a revolutionary, beautiful timepiece.

Version 2 split “Disk Clock” into multiple different widgets. Rather than having to flip to the back and configure multiple intersecting disk sets, each widget has only one set of disks. If you want multiple levels of detail, simply install multiple widgets. The freed up space on the backside allows certain clocks to expose settings that weren’t available previously, such as configuring the bedtime overlay.

Take a look at the available Dashboard Widgets. (If you don’t see a favorite face, be patient. And let us know what you miss.)

For Chrome, version 2.5 has some internal restructuring, smaller code, and less visible seams between color wedges.

I’ve quit listing time-of-day since I no longer have a clock. I’m keeping time by the sun.

Why am I doing this? Out of disgust with Daylight Savings Time. I get up at dawn and don’t care what Washington wants to call it. The cost and confusion of changing clocks twice a year is ridiculous. Especially when the dates of doing so also change. I’ll live on local time.


Unix Disk

Disk Clock takes the idea of clock and turns it inside-out by moving the faces instead of the hand. Unix Disk graphically displays the time until the year 2038 problem, which has been in the news bit recently.

One flaw with the current representation is that it only shows 31 bits – the sign bit overflow is not represented.

Disk Daylight Savings is available as a Dashboard Widget, or a live Web App directly from this site.



TrueTyme provides a graphical representation of the sun and moon, with an emphasis on the effects of the diurnal cycle and other natural cycles on mood and even weight. It packs a lot of features into it’s android app (web demo also available), including a tutorial and multiple display modes. Despite it’s focus on natural cycles, it’s still grounded in twelve hour periods, although it seems to have shifted them to be day and night.

The Present Received

It’s Daylight Crazy Time

Disk Clock takes the idea of clock and turns it inside-out by moving the faces instead of the hand. Daylight crazy time regularly turns us inside with shifting schedules. Disk Daylight Savings graphically shows the times of year when you need to be looking at the nearest Sunday to change your clocks. The color shows the degree if misalignment between the clocks and solar noon, changing from a sunny yellow when it’s well aligned, to red when things are out of whack – with a noticeable shift when the clocks get skewed.

The daylight crazy information comes from your computer’s clock – it only operates in the computer’s local time. Getting good solar alignment requires that the latitude and longitude be set – otherwise everything will go red.

Whitehouse Petition: Eliminate Daylight Crazy Time

Eliminate the bi-annual time change caused by Daylight Savings Time

Time is an archaic practice in our modern society.

The original reasons for the policies are no longer applicable, and the most cited reason for keeping DST (energy savings) has never been shown to be true.

Some industries still like DST (like sporting equipment retailers), but there are many more who dislike the changed hours (like television).

The real issue, however is not the later hours or extra sunlight. Studies have shown that changing the clocks is responsible for health problems (including increased heart attack and vehicular accident risks) and leads to hundreds of thousands of hours of lost productivity in workplaces across the country. Also: It’s really annoying.

We should either eliminate DST or make it the year-round standard time for the whole country.

Chrome Apocalypse Averted

Disk Clock chrome apps are now published in manifest version 2, so they will continue to work in upcoming versions. It was also possible to publish Disk Century and Disk Lifetime

Happy Birthday: Disk Lifetime

It’s my birthday – and I’m giving you a present. Track your own birthday with Disk Lifetime.

Disk Clock takes the idea of clock and turns it inside-out by moving the faces instead of the hand. Solar year broadens the horizon to encompass a full year. Disk Lifetime puts time on an intensely personal scale. While none of us knows when we’ll leave this life, Disk Lifetime presents a reasonable guess – one lifetime, four generations, and eighty birthdays, set against the tropical zodiac. Stop for a moment to consider where you’ve been in life, where you’re going, and how you are going to use the precious birthdays you have left.

Disk Lifetime is available as a Dashboard Widget, or a live Web App directly from this site. (Chrome has introduced breaking changes and isn’t allowing new apps into the webstore.)

Partly Cloudy Weather App

Partly Cloudy

Partly Cloud has a website with an obnoxious animated header, but thankfully the same design sense has not infected the app. The iPhone app uses the clock face primarily for showing weather, but they also work in daylight hours. Unfortunately they still use a fixed fixed clock face, and some of it is hidden by a fade-out effect to address the wrap-around problem. Partly Cloudy uses consecutive rings for different types of information (wind/rain, temperature, time scale), and then uses a toggle to switch between different time scales. On the whole it’s a well designed piece of software that follows very much in the spirit of Disk Clock.
