public class TrieDateField extends TrieField implements DateValueFieldType
Date Format for the XML, incoming and outgoing:
A date field shall be of the form 1995-12-31T23:59:59Z The trailing "Z" designates UTC time and is mandatory (See below for an explanation of UTC). Optional fractional seconds are allowed, as long as they do not end in a trailing 0 (but any precision beyond milliseconds will be ignored). All other parts are mandatory.
This format was derived to be standards compliant (ISO 8601) and is a more restricted form of the canonical representation of dateTime from XML schema part 2. Examples...
Note that TrieDateField is lenient with regards to parsing fractional seconds that end in trailing zeros and will ensure that those values are indexed in the correct canonical format.
This FieldType also supports incoming "Date Math" strings for computing
values by adding/rounding internals of time relative either an explicit
datetime (in the format specified above) or the literal string "NOW",
ie: "NOW+1YEAR", "NOW/DAY", "1995-12-31T23:59:59.999Z+5MINUTES", etc...
-- see DateMathParser for more examples.
NOTE: Although it is possible to configure a TrieDateField
instance with a default value of "NOW" to compute a timestamp
of when the document was indexed, this is not advisable when using SolrCloud
since each replica of the document may compute a slightly different value.
TimestampUpdateProcessorFactory is recommended instead.
Explanation of "UTC"...
"In 1970 the Coordinated Universal Time system was devised by an international advisory group of technical experts within the International Telecommunication Union (ITU). The ITU felt it was best to designate a single abbreviation for use in all languages in order to minimize confusion. Since unanimous agreement could not be achieved on using either the English word order, CUT, or the French word order, TUC, the acronym UTC was chosen as a compromise."
