It's a standard C library function that Ruby just provides an interface to. That's not an excuse, of course, but there are more important and Ruby-specific things whose documentation is a higher priority. The standard manual page for strftime from section 3 of the Unix Programmer's Manual is reproduced in various places around the web. The first google hit for "strftime man page" was this: http://www.cgi101.com/class/ch16/envman.cgi?strftime
