Native implementation of DateTime class?

Legacy UDK Programming and UnrealScript
1

I have had to implement my own class for working with DateTime objects (comparing dates, determining time difference, time epoch/timestamps, etc).

Is there nothing already available in the native code that I have missed?

I know UE4 has the FDateTime class: https://docs.unrealengine.com/en-US/…ime/index.html

But i don’t see anything in UnrealScript.

Are you using this?



local int Day, DayOfWeek, Month, Year, Hour, Minute, Second, MSecond;
GetSystemTime(Year, Month, DayOfWeek, Day, Hour, Minute, Second, MSecond);

@Nathaniel3W Yes I’m aware of this (it’s what I’m using in the class i implemented).

There is no handling for comparing time objects, getting time elapsed, checking days in a given month, leap years, unix epoch timestamps. No way to perform logic operators on a DateTime objects.

Like saying date1 < date2 for instance.

Or checking time elapsed from date1.

Almost all programing languages I’ve used provide a DateTime class, it’s just weird that it’s absent from US.

What I have implemented is mostly fine. There are just a few holes in it (like not accounting for leap-years).

there are some macros in core folder in global.uci file at the bottom, not sure if these will help you out.

/** This is a slick way to to do thing like: TimeSince(LastFoo) < Delta where the macro makes it a lot easier to read what the code is doing /
define TimeSince(Time) (WorldInfo.TimeSeconds - Time)
/ This is used for classes which are object derived and do not have access to WorldInfo so we need to pass in the Actor to get a worldinfo **/
define TimeSinceEx(Actor,Time) (Actor.WorldInfo.TimeSeconds - `Time)

Thanks @gamepainters. But those are related to game time, not system DateTime.
