Timestamp type¶

The Timestamp type is immutable and contains two fields: timestamp and value.

immutable Timestamp{T}
    timestamp::Union(Date,DateTime,Days)
    value::T
end

timestamp¶

The timestamp of the Timestamp type can hold one of three types:

Type	Representation
Date	Daily intervals and larger
DateTime	Intervals less than 1 day
Day	Daily span in integer format

value¶

Since the value field is parameterized, it can hold any type. We will see later when constructing an Array{Timestamp} that this allows for a pseudo-heterogenous array structure.
