Timestamp issue

[vasquezito]

Thanks for this library niXman! I'm having issues with receiving (I think!) the correct timestamp. The date is in the future and it doesn't contain the last 3 digits for the ms, it almost looks like it's missing data. Here is my output

c:\Users\vasquez\source\repos\ConsoleApplication1\Debug>ConsoleApplication1.exe server_time=3841850106

local_time=1610159618498

price: {"symbol":"BTCUSDT","price":"40066"}

Any ideas?

hi,

please provide me the complete example because I can't confirm this using my code...

[vasquezito]

Here is the code. Not much going on, just working from your example. I'm building it in Visual Studio 2019 Community Edition as an x86 console application, MSVC 14.28.29333 and compiler version below

please remove all unnecessary code that is not related to the essence of the problem.

[vasquezito]

After some debugging I've found the problem originating in types.hpp, specifically in the struct server_time_t where I replaced std::size_t serverTime; with std::int64_t serverTime;. Seems to be working correct now and I receive the correct format of the timestamp.

[niXman]

that is, you made changes to the code that you did not tell me about, and I had to waste my time on the problem you created?!

fck!
