type Timestamp

/ Timestamp is a 64-bit signed integer representing an elapsed time since a / fixed epoch, stored in either of four units: seconds, milliseconds, / microseconds or nanoseconds, and is optionally annotated with a timezone. / / Timestamp values do not include any leap seconds (in other words, all / days are considered 86400 seconds long). / / Timestamps with a non-empty timezone / ------------------------------------ / / If a Timestamp column has a non-empty timezone value, its epoch is / 1970-01-01 00:00:00 (January 1st 1970, midnight) in the *UTC* timezone / (the Unix epoch), regardless of the Timestamp's own timezone. / / Therefore, timestamp values with a non-empty timezone correspond to / physical points in time together with some additional information about / how the data was obtained and/or how to display it (the timezone). / / For example, the timestamp value 0 with the timezone string "Europe/Paris" / corresponds to "January 1st 1970, 00h00" in the UTC timezone, but the / application may prefer to display it as "January 1st 1970, 01h00" in / the Europe/Paris timezone (which is the same physical point in time). / / One consequence is that timestamp values with a non-empty timezone / can be compared and ordered directly, since they all share the same / well-known point of reference (the Unix epoch). / / Timestamps with an unset / empty timezone / ----------------------------------------- / / 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 non-existent. 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.
