(adsbygoogle = window.adsbygoogle || []).push({});after-content-x4char * asctime (const struct tm* tmptr )  Converted tmptr in a character string in format Www Mmm dd hh:mm:ss yyyy , Or Www is the day of the week, Mmm is the month in letters, dd The day of the month, hh:mm:ss is time, and yyyy is the year. The chain is followed by a return to the line and an end of the chain, for a total of 26 characters. The result chain is allocated statically and shared by the functions ctime And asctime . Each time one of the two functions is called, the content this chain is replaced. clock_t clock (void)  Returns an approximation of the processor time used by the process. char* ctime (const time_t* timer )  Converts the value timer in a chain in the same format as asctime . The returned chain is allocated statically in a shared area with asctime . ctime uses the internal buffer of gmtime And localtime As a return pointer, a call to this function will therefore cause crushing. double difftime (time_t Timer2 , time_t Timer1 )         (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Returns the difference, expressed in seconds between two moments. struct tm* gmtime (const time_t* timer )  Converts a type value time_t In a TM structure in UTC time. This structure is allocated statically and shared by the functions gmtime , localtime And ctime . Each time one of these functions is called, the content of the structure is crushed. struct tm* gmtime_r (const time_t* timer , struct tm* result )  Converts a type value time_t In a TM structure in UTC time. The date is stored in the TM structure pointed out by result . This is a version compatible with the threads of gmtime . struct tm* localtime (const time_t* timer )  Converts a type value time_t in a TM structure at local time. This structure is allocated statically and shared by the functions gmtime , localtime And ctime . Each time one of these functions is called, the content of the structure is crushed. time_t mktime (struct tm* ptm )  Converts a structure tm in a type of type time_t . mktime Check the TM structure, by correcting the values \u200b\u200bof its attributes if they are poorly informed, and translates this structure into a value time_t which has returned. The original values \u200b\u200bof the fields tm_wday And tm_yday (day of week and year) of ptm are ignored, but the fields are filled with the values \u200b\u200bthat correspond to the calculated date. The value of tm_day is not checked until tm_wday And tm_yday are determined. In the event of an error, the function returns the value (time_t)-1 . time_t time (time_t* timer )  Gives current time. The value is stored in the object pointed out by timer . In the case where timer is zero, the value has only passed as a result of the function. Standard C specifies that the type time_t is arithmetic, but that its encoding is not specified, which makes this type practically opaque. The POSIX standard specifies that time_t contains the number of seconds since first is January 1970 (Unix time). size_t strftime (char* s , size_t n , const char* format , const struct tm* tptr )  Formed at the structure tm in a character string, written in s , which contains at most n characters. CLK_PER_SEC Constant that defines the number of clock blows per second. It is used by the function clock() . CLOCKS_PER_SEC Another name of CLK_PER_SEC used by a few libraries. CLK_TCK An obsolete macro from CLK_PER_SEC. clock_t Type of data returned by Clock (). Generally defined by types int or long int . time_t Type of data returned by Time (). Generally defined by types int or long int . struct tm Human representation and calendar of dates. Calendar [ modifier | Modifier and code ] The human representation of dates (“Broken-Down Time” in English) is represented in the standard library C by the structure struct  tm Here are the members: Member Description int tm_hour  Time (0 – 23) int tm_isdst Indicator on the offset between winter and summer time: is 1 if the discrepancy is active, 0 if it is not and a negative value if the information is not available. int tm_mday Day of the month (1 – 31) int tm_min minutes (0 – 59) int tm_mon months (0 – 11, 0 corresponds to January) int tm_sec seconds (0 – 59) int tm_wday Day of the week (0-6, 0 corresponds to Sunday) int tm_yday Day of year (0 – 365) int tm_year number of years since 1900 (in)  The GNU C Library ReferenceManual , July 6, 2001 ( read online ) , \u00ab\u00a0Calendar Time\u00a0\u00bb (in)  The Open Group BaseSpecifications , December 9, 2008 ( read online ) , \u00abGmtime\u00bb       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4"},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/all2en\/wiki32\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/all2en\/wiki32\/timeh-wikipedia\/#breadcrumbitem","name":"TIME.h \u2014 Wikipedia"}}]}]
