///
///   For example, the timestamp value 0 with the timezone string "Europe/Paris"

///
/// One consequence is that timestamp values with a non-empty timezone
/// can be compared and ordered directly, since they all share the same

/// -----------------------------------------
///
/// If a Timestamp column has no timezone value, its epoch is
/// 1970-01-01 00:00:00 (January 1st 1970, midnight) in an *unknown* timezone.
///
/// Therefore, timestamp values without a timezone cannot be meaningfully
/// interpreted as physical points in time, but only as calendar / clock
/// indications ("wall clock time") in an unspecified timezone.
///
///   For example, the timestamp value 0 with an empty timezone string
///   corresponds to "January 1st 1970, 00h00" in an unknown timezone: there
///   is not enough information to interpret it as a well-defined physical
///   point in time.
///
/// One consequence is that timestamp values without a timezone cannot
/// be reliably compared or ordered, since they may have different points of
/// reference.  In particular, it is *not* possible to interpret an unset
/// or empty timezone as the same as "UTC".
///
/// Conversion between timezones
/// ----------------------------
///
/// If a Timestamp column has a non-empty timezone, changing the timezone
/// to a different non-empty value is a metadata-only operation:
/// the timestamp values need not change as their point of reference remains
/// the same (the Unix epoch).
///
/// However, if a Timestamp column has no timezone value, changing it to a
/// non-empty value requires to think about the desired semantics.
/// One possibility is to assume that the original timestamp values are
/// relative to the epoch of the timezone being set; timestamp values should
/// then adjusted to the Unix epoch (for example, changing the timezone from
/// empty to "Europe/Paris" would require converting the timestamp values
/// from "Europe/Paris" to "UTC", which seems counter-intuitive but is
/// nevertheless correct).
///
/// Guidelines for encoding data from external libraries
/// ----------------------------------------------------
///
/// Date & time libraries often have multiple different data types for temporal
/// data. In order to ease interoperability between different implementations the
/// Arrow project has some recommendations for encoding these types into a Timestamp
/// column.
///
/// An "instant" represents a physical point in time that has no relevant timezone
/// (for example, astronomical data). To encode an instant, use a Timestamp with
/// the timezone string set to "UTC", and make sure the Timestamp values
/// are relative to the UTC epoch (January 1st 1970, midnight).
///
/// A "zoned date-time" represents a physical point in time annotated with an
/// informative timezone (for example, the timezone in which the data was
/// recorded).  To encode a zoned date-time, use a Timestamp with the timezone
/// string set to the name of the timezone, and make sure the Timestamp values
/// are relative to the UTC epoch (January 1st 1970, midnight).
///
///  (There is some ambiguity between an instant and a zoned date-time with the
///   UTC timezone.  Both of these are stored the same in Arrow.  Typically,
///   this distinction does not matter.  If it does, then an application should
///   use custom metadata or an extension type to distinguish between the two cases.)
///
/// An "offset date-time" represents a physical point in time combined with an
/// explicit offset from UTC.  To encode an offset date-time, use a Timestamp
/// with the timezone string set to the numeric timezone offset string
/// (e.g. "+03:00"), and make sure the Timestamp values are relative to
/// the UTC epoch (January 1st 1970, midnight).
///
/// A "naive date-time" (also called "local date-time" in some libraries)
/// represents a wall clock time combined with a calendar date, but with
/// no indication of how to map this information to a physical point in time.
/// Naive date-times must be handled with care because of this missing
/// information, and also because daylight saving time (DST) may make
/// some values ambiguous or nonexistent. A naive date-time may be
/// stored as a struct with Date and Time fields. However, it may also be
/// encoded into a Timestamp column with an empty timezone. The timestamp
/// values should be computed "as if" the timezone of the date-time values
/// was UTC; for example, the naive date-time "January 1st 1970, 00h00" would
/// be encoded as timestamp value 0.
