Question

I\'ve been looking for a way to convert a string (in Epoch time) into a date.

Basically, I need to take this: 1360440555 (in string form) and make it in

You could use %s (GNU extension), to convert POSIX timestamp given as a string to the broken-down time tm:

#define _XOPEN_SOURCE
#include 
#include 
#include 

int main() {
    struct tm tm;
    char buf[255];

    memset(&tm, 0, sizeof(struct tm));
    strptime("1360440555", "%s", &tm);
    strftime(buf, sizeof(buf), "%b %d %H:%M %Y", &tm);
    puts(buf); /* -> Feb 09 20:09 2013 */
    return 0;
}

Note: the local timezone is UTC (with other timezone the result is different).
