For Temporal.Instant instances, the initial value is the {{jsxref(\"Temporal/Instant/Instant\", \"Temporal.Instant()\")}} constructor. {{jsxref(\"Temporal/Instant/epochMilliseconds\", \"Temporal.Instant.prototype.epochMilliseconds\")}} : Returns an integer representing the number of milliseconds elapsed since the Unix epoch (midnight at the beginning of January 1, 1970, UTC) to this instant.
