kompat-time

A Kotlin compatibility layer for constructing and manipulating Java Time.

Compatibility

kompat-time is built on the Java Time API defined in JSR-310 and implemented in Java 8. Therefore it should only be used on JVM's with Java >= 8. Sorry no Android or JS targeting.

Builders

import nz.ahw.kompat.time.*
import nz.ahw.kompat.time.units.*

val ld: LocalDate = LocalDate(2017, Month.DECEMBER, 8) // 2017/12/08
val lt: LocalTime = LocalTime(16, 40) // 16:40
val ldt: LocalDateTime = LocalDateTime(ld, lt) // 2017-12-08T16:40

val p: Period = Period(2.years) // P2Y
val d: Duration = Duration(4.hours) // PT4H

val t: Instant = Instant(150.seconds) // 1970-01-01T00:02:30Z

Extensions

// Arithmetic operations 
val p2: Period = p + 4.months - 3.days // P2Y4M-3D
val d2: Duration = d + 10.minutes // PT4H10M

val ld2: LocalDate = ld + 2.days // 2017/12/10

// Infix Functions
val ldt2: LocalDateTime = ld atTime lt // 2017-12-08T16:40


// With Functions
val ld3: LocalDate = ld.with(month = Month.OCTOBER)

Date Literals

import knz.ahw.kompat.time.literal.dates.*

// DMY (Little Endian)
val date: LocalDate = 8/Nov/2017

// MDY (Middle Endian)
val date: LocalDate = Nov/8/2017

// YMD (Big Endian)
val date: LocalDate = 2017-Nov-8
