Carbon dating boot
As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.
The current beta of CCC 4 already works with APFS insofar as CCC can copy files to and from that filesystem.
Note: I live in Ottawa, Ontario, Canada and if the timezone is not specified in the examples then the default of 'America/Toronto' is to be assumed.
Typically Ottawa is -0500 but when daylight savings time is on we are -0400.
The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.
