Time

  | ZonedDateTime

A Time represents a clock time without any date components.

Properties

Name	Type	Description
`hour`	`number`	The hour, numbered from 0 to 23.
`minute`	`number`	The minute in the hour.
`second`	`number`	The second in the minute.
`millisecond`	`number`	The millisecond in the second.

Methods

Method	Description
`constructor( hour: number, minute: number, second: number, millisecond: number ): void`
`copy(): Time`	Returns a copy of this time.
`add( (duration: TimeDuration )): Time`	Returns a new `Time` with the given duration added to it.
`subtract( (duration: TimeDuration )): Time`	Returns a new `Time` with the given duration subtracted from it.
`set( (fields: TimeFields )): Time`	Returns a new `Time` with the given fields set to the provided values. Other fields will be constrained accordingly.
`cycle( field: TimeField, amount: number, options?: CycleTimeOptions ): Time`	Returns a new `Time` with the given field adjusted by a specified amount. When the resulting value reaches the limits of the field, it wraps around.
`toString(): string`	Converts the time to an ISO 8601 formatted string.
`compare( (b: AnyTime )): number`	Compares this time with another. A negative result indicates that this time is before the given one, and a positive time indicates that it is after.

A CalendarDateTime represents a date and time without a time zone, in a specific calendar system.

Properties

Name	Type	Description

`era`	`string`	The calendar era for this date, e.g. "BC" or "AD".
`year`	`number`	The year of this date within the era.
`month`	`number`	The month number within the year. Note that some calendar systems such as Hebrew may have a variable number of months per year. Therefore, month numbers may not always correspond to the same month names in different years.
`day`	`number`	The day number within the month.
`hour`	`number`	The hour in the day, numbered from 0 to 23.
`minute`	`number`	The minute in the hour.
`second`	`number`	The second in the minute.
`millisecond`	`number`	The millisecond in the second.
