Re: [Haskell-cafe] threadDelay delays less time than expected (Windows)

Not to be infuriating, but I think you should check and re-check your tooling is not using 32 bit values at any particular point. Notice: (fromIntegral (86400000000 `mod` 2^32)) / 10^6 ~ 500 seconds which is your observation. Any time you depend on `Int` to represent numbers near or greater than 2^28, or perhaps 2^31 in practice, you should think hard about bounds and implications regarding portability anyway. -Thomas On Wed, Dec 28, 2016 at 4:05 PM, Lian Hung Hon wrote:

Dear Tom/Yitz,

Just tested, returns False. I'm on 64 bit by the way. What should I do from here?

If True, your machine (32-bit?) is probably overflowing the Int

Good point. Even if False on Lian's Windows machine, it could be there is some 32-bit value somewhere in the Windows implementation that causes this.
