Preface-simple requirements for time
Code related to the time business. It basically belongs to the bottom layer of the framework. The changes involved are very small. When I used to
C language time. h clock () function test program running time method, time. hclock
The clock () function can be used to calculate the execution time of a program in C language.

The date and time functions are in time. h, it mainly represents the clock_t type of the processor clock, time_t type of time, number of tick messages per second clocks_per_sec, struct TM structure describing the calendar time, function clock, time,
The basic time service provided by the Unix kernel is the number of seconds that have elapsed since 00:00:00, January 1, January 1, 1970 AD, The International Standard Time. This number of seconds is represented by the Data Type time_t.

1. Obtain the time:Use the time () function to obtain the calendar time. Its prototype is time_t time (time_t * timer );

The following describes the time functions in C/C ++ for your reference.
1. Definition of time
C/C ++ has many time-related operations worth your attention. Recently, many netizens in the Technical Group have asked questions about time operations,
This is a standard greedy algorithm. The general meaning of the question is: Now I am giving you some water ponds. Now the child is in the pond 1. Now I am going to fish. At the beginning, Each pond has a fixed number of fish, the number of fish
When the HTTP request contains the header of the if-xxx style, the server will judge the attached condition, and the request will be executed only if the specified condition is true. Such requests have five headers, namely If-modified-since,
How to obtain system time in C Language
How to obtain the time in C language? How accurate?
1 use time_t time (time_t * timer) to be accurate to seconds
2 using clock_t clock (), the CPU time is accurate to 1/clocks_per_sec.
3. Calculate the time
Function category:1. Set the time: settimeofday, tzset2. Get time: time, ftime, gettimeofday3. Time Format Conversion: mktime, strftime; gmtime, localtime; asctime, ctime4. Others: Clock, difftime
Asctime: represents the time and date in string
