Functions¶

Name	Summary
adjustedTo	common `fun adjustedTo(newTimeZone: TimeZone): ZonedDateTime` Changes the time zone of a ZonedDateTime, adjusting the date, time, and offset such that the instant represented by it remains the same.
compareTo	common `open operator fun compareTo(other: TimePoint<*>): Int` Compares this time point with another time point.
copy	common `fun copy(dateTime: DateTime = this.dateTime, offset: UtcOffset = this.offset, zone: TimeZone = this.zone): ZonedDateTime` `fun copy(date: Date = this.date, time: Time = this.time, offset: UtcOffset = this.offset, zone: TimeZone = this.zone): ZonedDateTime` `fun copy(year: Int = this.year, dayOfYear: Int = this.dayOfYear, hour: Int = this.hour, minute: Int = this.minute, second: Int = this.second, nanosecond: Int = this.nanosecond, offset: UtcOffset = this.offset, zone: TimeZone = this.zone): ZonedDateTime` `fun copy(year: Int = this.year, month: Month = this.month, dayOfMonth: Int = this.dayOfMonth, hour: Int = this.hour, minute: Int = this.minute, second: Int = this.second, nanosecond: Int = this.nanosecond, offset: UtcOffset = this.offset, zone: TimeZone = this.zone): ZonedDateTime` `fun copy(year: Int = this.year, monthNumber: Int, dayOfMonth: Int = this.dayOfMonth, hour: Int = this.hour, minute: Int = this.minute, second: Int = this.second, nanosecond: Int = this.nanosecond, offset: UtcOffset = this.offset, zone: TimeZone = this.zone): ZonedDateTime` Returns a copy of this date-time with the values of any individual components replaced by the new values specified.
