 <div class="textblock"><p>Represents either a (1) date and time, (2) a date with an undefined time, or (3) a time with an undefined date. In all cases, times have up to nanosecond resolution and the minimum and maximum dates are 1400-01-01 and 10000-12-31. This type is similar to Postgresql TIMESTAMP WITHOUT TIME ZONE datatype and MySQL's DATETIME datatype. Note that because TIMESTAMP does not contain time zone information, the time zone must be inferred by the context when needed. For example, suppose the current date and time is Jan 15 2015 5:37:56 PM PST: SELECT NOW(); &ndash; Returns '2015-01-15 17:37:56' - implicit time zone of NOW() return value is PST SELECT TO_UTC_TIMESTAMP(NOW(), "PST"); &ndash; Returns '2015-01-16 01:54:21' - implicit time zone is UTC, input time zone specified by second parameter. Hive describes this data type as "Timestamps are interpreted to be timezoneless and
 stored as an offset from the UNIX epoch." but storing a value as an offset from Unix epoch, which is defined as being in UTC, is impossible unless the time zone for the value is known. If all files stored values relative to the epoch, then there would be no reason to interpret values as timezoneless. TODO: Document what situation leads to #2 at the top. Cases #1 and 3 can be created with literals. A literal "2000-01-01" results in a value with a "00:00:00" time component. It may not be possible to actually create case #2 though the code implies it is possible. For collect timings, prefer the functions in <a class="el" href="time_8h.html">util/time.h</a>. If this class is used for timings, the local time should never be used since it is affected by daylight savings. Also keep in mind that the time component rolls over at midnight so the date should always be checked when determining a duration. </p>
