DailyDirt: Time, Time, Time. See What's Become Of..

from the urls-we-dig-up dept

With the Apple Watch available now, maybe more people will be interested in wearing fancy watches again -- instead of just relying on their phones. Fancy watches once focused on telling time with extreme accuracy, but then digital watches made it really cheap to keep accurate time that was more than "good enough" for most folks. It used to be annoying to need to adjust clocks for daylight savings and power outages, but as more and more clocks are connected to the internet (except for ovens and some cheap alarm clocks), we barely need to think about how to change the time on a clock (who owns a VCR anymore?). Check out these links on accurate time keeping. After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

    That's a very real problem that has nothing to do with leap seconds. See http://en.wikipedia.org/wiki/Year_2038_problem

    I still think it was a mistake to store the time as the amount of seconds that have passed since some arbitrary date.

    Sure, storing the date as a 32-bit number might have been the most efficient way to store the date and time, saving a few bytes, but then they would need to add extra code to convert that 32-bit number back into a human-readable format. If they'd used separate bytes for the seconds, minutes, hours, days, months and year, they could have made up the difference in much simpler code used to convert those bytes into human-readable date formats. At the very least, they should have used a single byte for the year and then they could have stored the rest of the time/date as an offset from that year. That would have given them more than 256 years for the cost of a single extra byte.
