Can someone will expalin to me What is atltime.h ? I don't know how this header works. I tried to search it on google but i didn't get an answer of what atltime. h is.

CodePudding user response：

Not MFC, but ATL. ATL (Active Template Library) is a set of header files that ships with Visual Studio for making Windows programming easier without having to pull in all of MFC. These headers implement C class libraries that do useful things for legacy Windows programming.

It appear that atltime.h has the declarations for the following classes:

CTime, CTimeSpan, CFileTime, etc...
