DatasetDateBucketCases

abstract class DatasetDateBucketCases : DatasetAggregationCases

The cases of the dataset contract (DatasetQueryBackendSpec, which extends this class and is the one a backend's test extends) on date buckets across a zone's offset changes. They hold the bucket rule (DateBuckets) at daylight saving's transitions, in a half-hour zone, at a half-hour change (Australia/Lord_Howe), at a change by seconds (Africa/Monrovia) and on the day of a change before 1970 (Asia/Shanghai's switch from local mean time). They read their table, ZONED, through aggregateZoned, over DatasetQueryFixtures' fixtures and hooks; see there for the chain of families this class is part of.
