Dates

Key Dates in Lifetime Blotter refers to a 1D-array of dates that correspond to the 1D-array of objects of type MultiDay Blotter supplied in Blotters
The iᵗʰ date is assumed to be the date when the corresponding iᵗʰ blotter is published.
If a particular transaction is missing from the iᵗʰ blotter, but exists in the (i-1)ᵗʰ blotter, it is considered as having been disposed exactly on the provided iᵗʰ date.
This assumption is sensible if the dates are consecutive in a business calendar sense.
If the dates are not consecutive, the assumption becomes arbitrary and provides a crude approximation to the actual but unknown disposal date.
