NAME

       fmt_iso8601 - write a date in ASCII conforming to ISO-8601

SYNTAX

       #include <libowfat/fmt.h>

       size_t fmt_iso8601(char *dest,time_t source);

DESCRIPTION

       fmt_iso8601   writes   a   date   in   ASCII   representation   as  ISO-8601  defines  it:
       "2014-05-27T19:22:16Z". ISO-8601 also allows to store a sub-second part and a  time  zone,
       but fmt_iso8601 does not support that.

       fmt_iso8601 does not append \0.

       If  dest  equals  FMT_LEN (i.e. is zero), fmt_iso8601 returns the number of bytes it would
       have written.

       The return value of fmt_iso8601 is 20 until Jan 1st 10000.

                                                                                   fmt_iso8601(3)
