Strings are null-terminated by definition.  According to the ANSI C
standard, strftime() gives either a string (if there is enough space)
or indeterminate buffer contents (otherwise) according to the ANSI C
standard.  The FreeBSD behaviour of truncating the string should not
be documented or depended on.  This means that the result of strftime()
should always be checked.  A fixed-size buffer may be too small because
the locale has long time-related strings.
