Functions in this category know about times and dates, datetimes, seconds or millisecond epoch times, and so forth.

Some of the functions in this category are designed to allow testing of UUID types which are usually designed to avoid determinism. This makes it possible to test systems which depend on UUIDs but which require determinism in test data. This is strictly for testing use. Breaking the universally-unique properties of UUIDs in production systems is a bad idea. Yet, in testing, this determinism is quite useful.

CqlDurationFunctions

Map a long value into a CQL Duration object based on a set of field functions.

ToEpochTimeUUID

Converts a long UTC timestamp in epoch millis form into a Version 1 TimeUUID according to RFC 4122. This means that only one unique value for a timeuuid can be generated for each epoch milli value, even though version 1 TimeUUIDs can normally represent up to 10000 distinct values per millisecond. If you need to access this level of resolution for testing purposes, use {@link ToFinestTimeUUID} instead. This method is to support simple mapping to natural timestamps as we often find in the real world.

For the variants that have a String argument in the constructor, this is a parsable datetime that is used as the base time for all produced values. Setting this allows you to set the start of the time range for all timeuuid values produced. All times are parsed for UTC. All time use ISO date ordering, meaning that the most significant fields always go before the others.

The valid formats, in joda specifier form are:

1. yyyy-MM-dd HH:mm:ss.SSSZ, for example: 2015-02-28 23:30:15.223
2. yyyy-MM-dd HH:mm:ss, for example 2015-02-28 23:30:15
