Ctime() Function Description in the C Language Thectime()function returns the pointer to a string in*strwhich contains the Unix time sent in time_t and converted to strings in datetime format. While the asctime() function converts the local or GMT time stored in the tm structure into a s...
Learn about the ctime function in C/C++, its uses, syntax, and how to convert time to a string representation.
ctime is an inline function which evaluates to _ctime64 and time_t is equivalent to __time64_t. If you need to force the compiler to interpret time_t as the old 32-bit time_t, you can define _USE_32BIT_TIME_T. Doing this will cause ctime to evaluate to _ctime32. Thi...
Note that the real C library ctime function puts a newline ('\n') character at the end of the string that this function does not. Also note that since the kernel has no concept of timezones, the returned time is always in GMT. 前...
In Visual C++ 2005, ctime_s is an inline function that evaluates to _ctime64_s and time_t is equivalent to __time64_t. If you need to force the compiler to interpret time_t as the old 32-bit time_t, you can define _USE_32BIT_TIME_T. Doing this will cause ctime...
