The util_strftime function translates a tm structure, which is a structure describing a system time, into a textual representation. It is a thread-safe version of the standard strftime function.


int util_strftime(char *s, const char *format, const struct tm *t);


The number of characters placed into s, not counting the terminating NULL character.


char *s is the string buffer to put the text into. There is no bounds checking, so you must make sure that the buffer is large enough for the text of the date.

const char *format is a format string, a bit like a printf string in that it consists of text with certain %x substrings. You can use the constant HTTP_DATE_FMT to create date strings in the standard Internet format. For more information, see the documentation on the printf function for the runtime library of your compiler. For more information on time formats, see the Sun Java System Web Server 7.0 Administrator’s Configuration File Reference.

const struct tm *t is a pointer to a calendar time (tm) structure, usually created by the function system_localtime or system_gmtime.
