Talk:Past-Seeing Alarm Clock/@comment-4273152-20160926055525/@comment-24588058-20160929225239

Well, according to Wikipedia, there have been different types of what you could feasibly call "alarm clocks". Citing an additional source, mechanical clocks for the home might have been around since the 13th century in Europe. The oldest alarm clock referenced in a book was a German clock made in 15th century Nuremburg. And user-settable alarm clocks date back to at least 15th century Europe as well, where pins were used to set the time you wanted the alarm to go off.
