How to get current time in milliseconds in Haxe?

Question

I need a function that returns the local time in milliseconds on the CPP target.

I tried Haxe's Date class, but Date.now() gives me the time in seconds.

Answer 1

Sys.time() * 1000.0 - http://api.haxe.org/Sys.html#time

Gives the most precise timestamp value (in seconds)

To be clear, I tried this and got millisecond resolution on the cpp target. Sys is available on cpp, cs, java, macro, neko, php and python.

Though I must say I find it kinda disturbing that this just has float precision. At least from C++, one is used to much better precision. – Ablaze

I suppose it's easier to implement a single method across platforms if you pass a float back. Here's how it's implemented for cpp: github.com/HaxeFoundation/hxcpp/blob/… – Impassion

they should really change the documentation and return milliseconds - else if useless unless you see this answer. – Sputum

@Ablaze Remember that haxe floats are 64-bit, so you actually get 56 bits of integer precision. – Karelian

Answer 2

You could try Date.now().getTime(), however:

Returns the timestamp of the date. It might only have a per-second precision depending on the platforms.

Doesn't work for cpp target. Maybe I should edit my question. – Macrophage

Yes, this only gives me per-second precision on the cpp target i.e: 1453822269000, 1453822270000... – Impassion

Answer 3

A fast way of getting a timestamp would be to use the haxe.Timer.stamp() method.

Example:

import haxe.Timer;

var timestamp:Float = Timer.stamp(); // return a timestamp in seconds with fractions

Note that the value itself might differ depending on platforms, only differences between two values make sense.
