Appendix C. strftime() Time Formats

strftime() is a standard C library function that formats date and time values according to a format defined in a specification string; it is composed of literal text interspersed with the conversion specifiers defined in Table C-1. These format specifiers are used in log format strings and SSI configuration options, as well as to define log file templates for the rotatelogs and cronolog log file rotation programs.
