I don't believe there is any need for cruise ships or manipulation of timezones in the answer. One twin born at 11:45pm on Feb 28, the other born at 12:15 am on March 1 will do nicely. When it is a leap year, their birthdays will be celebrated two days apart.
This is a high end espresso preparation device. The platinum tamper is shown at center. When dropped from 6” onto the grounds (use the measuring device secreted in the handle), it will perfectly tamp coffee grounds which have been previously passed through the number 1 screen, and caught on the number 2 screen. The brass carrying case for the screens is visible at bottom right. This screening assures sufficient grind while allowing the fines to pass through, eliminating the goaty flavor present in so many randomly ground coffees. The ceramic housing for the grinding apparatus is visible in the box, but the platinum burrs do not appear to be present. This set also includes coffee filters (in box) hand made from the pulp of wild-sourced tupelo trees not less than 75 years old. Based on the condition of the tupelo wood carrying case, and the design of the tamper, I’d estimate this set is at least 75 years old, with an estimated value of $1325.
