It looks like a clock. In a way, it is, but it’s not meant to tell the current time. Instead, the Time Since Launch Capsule marks the passage of it from an event of your choosing. Pull the pin and it begins counting up, showing the days, hours, minutes, and seconds on a pair of LCDs, stored safely inside a handsome borosilicate glass tube with galvanized aluminum endcaps. Use it to mark the birth of a child, a personal achievement, or any other momentous event, and know that you’ll be reminded every time you look at it — or at least until the 2,738-year timer runs out of room. Just be careful, once the pen has been pulled, the timer cannot be reset.
