My C++ port of the .NET DateTime struct

DateTimePlusPlus

This is a small C++ library designed to mimic the behavior of System.DateTime and System.TimeSpan from C#. It is not meant to be a precise port. Rather, the only standard is that the classes make use of the same 64-bit signed integer 'ticks' value (representing 100-nanosecond intervals since January 1, 0001).

Requirements

The project files are for the Code::Blocks IDE. See http://www.codeblocks.org/ for more information. If you want to submit other build files, submit a patch!

The DateTime and TimeSpan classes are completely self-contained and portable. They should work as is across any compiler or platform. (If they don't, submit a patch!)

On the side, there is some native code for obtaining high resolution timestamps. The Windows code makes use of the standard Win32 API. The UNIX code makes use of clock_gettime from time.h.

License

All of this code is in the public domain. Use it for whatever you like. It is strictly research for me in making good, clean time-related tools.

If you have a contribution, submit a pull request! All I ask is that you allow your contributions into the public domain as I have done. Aside from that, I just want to make these tools better and better.

datetimeplusplus's Issues

Convert loop-based math to direct math calculations

The Year, Month, and Day functions in the DateTime class get the right answers, but they depend on loops to find those answers. There should be a way to arrive at the correct answer without having to loop through ever year, month and day the way I did.

Add check in DateTimePlusPlus/DateTime.cpp

    if (InRange(year, 1, 9999) &&
        InRange(month, 1, 12) && // <<<< !!!!! 
        InRange(day, 1, DaysInMonth(month, year)) &&
        InRange(hour, 0, 23) &&
        InRange(minute, 0, 59) &&
        InRange(second, 0, 59) &&
        InRange(millisecond, 0, 999) &&
        InRange(microsecond, 0, 999) &&
        InRange(ticks, 0, 9))
