hey! what would be the best way to implement NaN with Long? I'm currently using Double.NaN to indicate invalid timestamps, but I'm leaning towards using milliseconds instead of seconds and using Long instead of Double. But I really like using NaN to indicate not set timestamp.

You’re probably better off using ISO-8601 formatted Strings for timestamps rather than millis, or any other number-type for representing timestamps. Java 8's LocalDate classes are really good for this.

this arent date timestamps

Why dont use nullable Long for this? Is there any specifc reason?

Ah, got it. Nullable numbers would be my suggestion too, instead of using a specific “magic number” for “not set”

yeah, I thought about using nullable, but it's not exactly the same, because I have situations where I have not existing time, or time set to NaN

You can filter it in the set of the field. Whenever you receive no time or NaN, put it to null

but then I can't distinguish between not set time or invalid time

Sorry, now I get it

I wasn't super clear about my requirements. My bad!

Yeah, if you create a type that has the flags you need, i guess it would be easier

OK, thanks, actually when I described better my needs, I also realized I will benefit from having a type 🙂 Because I can also add computed properties returning seconds 🙂

😄

The down side is I need to implement a couple of operators

What if you extend Long (or Double)?

great idea! 🙂
