The localtime function is used in processing time to convert a UTC time to a local time:
[Cpp]# Include Time_t tmNow = time (NULL );Tm * ptmNow = localtime (& tmNow); // the equivalent value of year, month, day, hour, minute, and second can be
1. time () function/* time-Gets the current calendar times of the computer system (Calender-time) * the function that processes DateTime is based on the return value of this function * * function prototype: * #include * *
struct Tm->time () localtime () gmtime ()structTM {int tm_sec;/*Represents the current number of seconds, the normal range is 0-59, but allowed to 61 seconds*/int tm_min;/*Represents current score, range 0-59*/int tm_hour;/*Number of hours from
In the C language, there are two functions that get the current time: LocalTime and Getlocaltime. They are widely used in procedures such as reconciliation.
In this paper, localtime and getlocaltime are described in detail, and their usage is
Struct tm-> time () localtime () gmtime (), localtimegmtime
Struct tm-> time () localtime () gmtime ()
Struct tm {int tm_sec;/* indicates the current number of seconds. The normal range is 0-59, but the value can be 61 seconds */int tm_min;/*
How to Implement C language for obtaining system time in Linux:
1. You can use the localtime function to obtain the values of year, month, day, hour, minute, and second respectively.
# Include // header file of C Language
# Include // I/O of C
You can run the following code directly to view the results:#!/usr/bin/python# Coding=utf-8Import Time # Introducing the time module# time Stamp:# each timestamp is represented by how long it has been since midnight on January 1, 1970 (calendar).#
The LocalTime function is used during processing time to convert a UTC time to local time: [CPP] #include time_t tmnow = times (NULL); tm *ptmnow = LocalTime (&A
Mp;tmnow)//From the TM structure can be taken to the date of the month and the minute
Linux uses C to get the current time, specifically as follows:Code (you can change the Clock_gettime to Time (NULL))?
12345678910
void getNowTime(){ timespec time; clock_gettime(CLOCK_REALTIME, &time); //获取相对于1970到现在的秒数 tm
Common time functions
I recently participated in a python project and found that I often encountered some common modules. I have to check them every time I use them. Finally, I decided to break through and summarize the common Python knowledge. The
