How to convert unix to DateTime?

UnhingedGoon · June 22, 2021, 5:32pm

Is there a way to convert unix time to date time in blueprints?

Example: 1624382981 → 2021-06-22 17:36:52

Thanks a lot.
Sometimes the answer can be way easier than you expect

Hey,
you could add the unix seconds to a MakeDateTime

I think the add node not working in ue5.1 anymore. Do you have another way to do this?

L1z4rD89 · March 9, 2023, 7:52pm

You could try this:

Or use C++, or use a python script or…

Good news the simple solution pointed out by L1z4rD89 is still working in UE5.1 ! The “add” node is buggy but by edditing the connexion inside the text editor it is possible ti make the connexion. And then you can just copy past :

Amazing! can I know the value you’ve put for Str Start date please?

L1z4rD89 · April 4, 2024, 3:32pm

Hey @Maddy13294

the string contains:

1970-01-01T00:00:00-

Here is a snippet

I know it was requested to be in BP, but sometimes creating big workarounds just not to use C++ is even more difficult.

This could be done pretty easily just by creating C++ class inherited from BlueprintFunctionLibrary.
Add this to .h:

	UFUNCTION(BlueprintCallable, BlueprintPure)
	static FDateTime UnixToDateTime(int64 UnixTime);

This to cpp:

FDateTime YourLibraryClassName::UnixToDateTime(int64 UnixTime)
{
	FDateTime DataTime;
	DataTime.FromUnixTimestamp(UnixTime);
	return DataTime;
}

Replace “YourLibraryClassName” with name of your class.

And pretty much it, you have such node available:

ysh11o · April 23, 2024, 7:20am

thanks for your code!
I test this code but always got 0001.01.01-00.00.00

ysh11o · April 23, 2024, 7:35am

FDateTime UTestBlueprintFunctionLibrary::UnixToDateTime(int64 UnixTime)
{
	return FDateTime(1970, 1, 1) + FTimespan(0,0,UnixTime);
}

I try to fix this error.
this is my code.

Sitiana · April 23, 2024, 8:36am

You are right, so sorry about this. Not sure why UE function is not working correctly, but this works fine for me:

FDateTime UTestBlueprintFunctionLibrary::UnixToDateTime(int64 UnixTime)
{
	return FDateTime(UnixTime * ETimespan::TicksPerSecond) + FDateTime(1970, 1, 1);
}

Note: this function is meant to use for short format Epoch (Unix) time. For those Timestamp formats that include nano seconds (for example: 17138563369669126) replace that line with this:

return FDateTime(UnixTime) + FDateTime(1970, 1, 1);
