The internal representation of dates in the Date object is the number of days from the start of the current epoch:
julia> d1 = Date("2018-08-15")julia> dump(d1)Date instant: Dates.UTInstant{Day} periods: Day value: Int64 736921
The day that corresponds to the integer 1 is January 1st, 1 A.D.:
julia> d1 = Date("2018-08-15")2018-08-15julia> d1 - Day(d1.instant.periods.value)+Day(1)0001-01-01
The internal representation of time in the DateTime objects is Millisecond-based:
julia> dt = DateTime("2018-08-15T18:22:55.123")julia> dump(dt)DateTime instant: Dates.UTInstant{Millisecond} periods: Millisecond value: Int64 63670040575123
