How to Implement C language for obtaining system time in Linux

The C language implementation method for obtaining system time in Linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. How to Implement C language for obtaining system time in Linux
# Include // Header file in C Language
# Include // C language I/O

Void main ()
{
Time_t now; // instantiate the time_t Structure
Struct tm * timenow; // instantiate the tm structure pointer
Time (& now );
// The time function reads the current time (International Standard time is not Beijing time), and then transmits the value to now

Timenow = localtime (& now );
// The localtime function converts the time now obtained from time to the time in your computer (that is, the region you set)

Printf ("Local time is % s \ n", asctime (timenow ));
// In the previous sentence, the asctime function converts the time into characters and outputs the time using the printf () function.
}

Note: time_t is a struct defined in time. h. The prototype of the tm struct is as follows:

Struct tm
{
Int tm_sec; // seconds 0-61
Int tm_min; // minutes 1-59
Int tm_hour; // hours 0-23
Int tm_mday; // day of the month 1-31
Int tm_mon; // months since jan 0-11
Int tm_year; // years from 1900
Int tm_wday; // days since Sunday, 0-6
Int tm_yday; // days since Jan 1, 0-365
Int tm_isdst; // Daylight Saving time indicator
};
