Question

I see that kotlin is getting its own implementation of `Duration` in the stdlib and I m wondering if it could also have its own version of `Date` that cleans up the mess that is Java s `Date` `DateTime` `LocalDate` `LocalDateTime`

But there are plans for kotlinx time

Mike · Answer

On JDK 8+ use the java time libraries They are as clean as time will get If you re stuck on older version Android then Joda Time is your best alternative

Mike · Answer

I hope kotlinx time just builds on extends java time

gildor · Answer

No Joda Time is not the best

gildor · Answer

Better to use ThreeTen Backport ThreeTenABP

DateTime LocalDate LocalDateTime aren t a mess

Mike · Answer

I agree with Jake it s the physical Date and Time that are a total mess Timezones DST leap years etc The java time library does a very good job of simplifying it as much as possible

Hullaballoonatic · Answer

By mess I mean that java s `Date` is completely replaced by `LocalDate` `DateTime` `LocalDateTime` which have a worse nomenclature They could all be consolidated into a single class imo

Mike · Answer

You ve forgotten ZonedDateTime Time is too complicated to easily be handled by one class The only time it s easy is if you only have one TZ to deal with and even that can have complications

Hullaballoonatic · Answer

Yeah and don t even start on historical events

Hullaballoonatic · Answer

leap seconds

Hullaballoonatic · Answer

it would help if we didn t try to divide the time it takes for the earth to orbit the sun by the time it takes for the fully rotate about its axis given those two cosmological events have no relation to one another at all

gildor · Answer

Yeah let s fix the world to simplify programmer s life otherwise it would be needed to read documentation for time API

jw · Answer

Well timezones and DST aren t really needed anymore Leap seconds then also not needed We control the software people Let s do this

I m all for a hard reset on humanity so we can start this whole quantifying date time thing from a more sensible position At the moment it is un refactorable
