And how to convert SYSTEMTIME to a time_t ?

<div class="content wysiwyg-content">
Hi, I have 2 SYSTEMTIME structures and I know how to calculate the 365-day difference between them. (FILETIME int64 etc)<br />
<br />
My problem is to calculate the total days in a 360-day format. Excel has a function Days360 which does that, but I couldn't find something in C++.<br />
<br />
How to do it?<br />
<br />

Calculating days in 360-format from SYSTEMTIME

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
