Radio controlled clock from serendipity-gifts.co.uk
We’ve all done it. Whether it’s ‘spring forward’ or ‘fall back’, it is so easy to forget to reset your clock and find yourself embarrassingly out of sync with the rest of the world.
Perhaps you woke up in the morning and went through your morning routine of getting ready for school, only to show up to an empty parking lot and locked school doors and realizing that the building hasn’t opened yet because classes don’t start for an hour! Or, even worse, you have been an hour late for work and walk in nonchalantly, and it is only when you see the unhappy look on the face of your boss when you realize the mistake you have made! Thankfully, there is no excuse anymore for such a time-blunder, thanks to radio controlled clocks.
When the first radio controlled clocks came out in the 1980s they were very large and expensive. However now compact radio controlled clocks are available in a number of designs suitable for home use and are quite affordable. Radio controlled clocks are not very much more expensive than regular clocks, and you can find some at a comparable price. They are quite an amazing and very accurate piece of time keeping technology.
