Obtain the current date and time
CTime tm = CTime: GetCurrentTime ();CString str = tm. Format ("% Y-% m-% d ");
In VC, we can use the CTime class to obtain the current date of the system. The usage is as follows:
CTime t = CTime: GetCurrentTime (); /
Atime, Mtime, CTime, called the timestamp of the file, is one of seven of the file's meta-information, which is included in the inode. whichAtime (Accesstime) refers to the time when the file was last accessed;Mtime (Modifytime) refers to the time

VC provides two types of date variables.
One is ctime. The disadvantage is that the year is only supported until 2038, and will not be supported in the future. If your project has a life cycle of 20 to 30 years, you can choose to use systemtime.
