Kind of puzzled about timestamps

[Ray Cote]

No conversation about time is complete without a nod to 'Calendrical
Calculations' by Reingold and Dershowitz:
https://www.cambridge.org/us/academic/subjects/computer-science/computing-general-interest/calendrical-calculations-ultimate-edition-4th-edition?format=HB&isbn=9781107057623

I have three editions of this on my shelf. Everytime I think I have a hard
problem to solve I peruse a chapter and then realize my problems aren't as
difficult as time...
