Class DBDateTimeColumnData

An object representing date time column data. The Deephaven date-time has nanonsecond precision, which is not representable by the .NET type, so while convenient, the method can result in loss of precision. The GetInt64(Int32) method provides access to full precision value, definend as nanoseconds since the epoch. The range of this value is implied by the range of nanoseconds representable by a 64-bit signed integer, with the exception of , which is used as a null-indicator. The and constants provide the representable range as values.
