Attributes
`hash`	Source Code`shared actual default Integer hash` Implementation compatible with `equals()` method. This implementation respect the constraint that if `x==y` then `x.hash==y.hash`. Refines `Object.hash`

Inherited Attributes
Attributes inherited from: `Object` `hash`, `string`
Attributes inherited from: `DateTimeBehavior<Element,DateType,TimeType>` `date`, `time`
Attributes inherited from: `Enumerable<Other>` `predecessor`, `successor`
Attributes inherited from: `Ordinal<Other>` `predecessor`, `successor`
Attributes inherited from: `ReadableDate` `day`, `dayOfEra`, `dayOfWeek`, `dayOfYear`, `weekOfYear`
Attributes inherited from: `ReadableMonth` `month`
Attributes inherited from: `ReadableTime` `hours`, `milliseconds`, `millisecondsOfDay`, `minutes`, `minutesOfDay`, `seconds`, `secondsOfDay`
Attributes inherited from: `ReadableYear` `leapYear`, `year`

Methods
`equals`	Source Code `shared actual default Boolean equals(Object other)` Two `DateTime`s are considered equals if they represent the same `Date` and `Time`. Refines `Object.equals`
`instant`	Source Code`shared formal Instant instant(TimeZone timeZone = ...)` Returns an instant from this `DateTime`. Parameters: `timeZone = tz.system`
`minus`	Source Code `shared formal DateTime minus(ReadablePeriod period)` Subtracts a specified period to this date and time.
`periodFrom`	Source Code `shared formal Period periodFrom(DateTime start)` Returns the period between this and the given DateTime. If this date is before the given date then return zero period.
`periodTo`	Source Code `shared formal Period periodTo(DateTime end)` Returns the period between this and the given DateTime. If this DateTime is after the given DateTime then return zero period.
`plus`	Source Code `shared formal DateTime plus(ReadablePeriod period)` Adds a specified period to this date and time.
`rangeTo`	Source Code `shared formal DateTimeRange rangeTo(DateTime other)` Returns the `DateTimeRange` between this and given `DateTime`.
