+ "Use FORMAT-STRING to format the time TIME, or now if omitted.
+TIME is specified as (HIGH LOW . IGNORED) or (HIGH . LOW), as returned by
+`current-time' or `file-attributes'.
+The third, optional, argument UNIVERSAL, if non-nil, means describe TIME
+as Universal Time; nil means describe TIME in the local time zone.
+The value is a copy of FORMAT-STRING, but with certain constructs replaced
+by text that describes the specified date and time in TIME:
+
+%Y is the year, %y within the century, %C the century.
+%G is the year corresponding to the ISO week, %g within the century.
+%m is the numeric month.
+%b and %h are the locale's abbreviated month name, %B the full name.
+%d is the day of the month, zero-padded, %e is blank-padded.
+%u is the numeric day of week from 1 (Monday) to 7, %w from 0 (Sunday) to 6.
+%a is the locale's abbreviated name of the day of week, %A the full name.
+%U is the week number starting on Sunday, %W starting on Monday,
+ %V according to ISO 8601.
+%j is the day of the year.
+
+%H is the hour on a 24-hour clock, %I is on a 12-hour clock, %k is like %H
+ only blank-padded, %l is like %I blank-padded.
+%p is the locale's equivalent of either AM or PM.
+%M is the minute.
+%S is the second.
+%Z is the time zone name, %z is the numeric form.
+%s is the number of seconds since 1970-01-01 00:00:00 +0000.
+
+%c is the locale's date and time format.
+%x is the locale's \"preferred\" date format.
+%D is like \"%m/%d/%y\".
+
+%R is like \"%H:%M\", %T is like \"%H:%M:%S\", %r is like \"%I:%M:%S %p\".
+%X is the locale's \"preferred\" time format.
+
+Finally, %n is a newline, %t is a tab, %% is a literal %.
+
+Certain flags and modifiers are available with some format controls.
+The flags are `_' and `-'. For certain characters X, %_X is like %X,
+but padded with blanks; %-X is like %X, but without padding.
+%NX (where N stands for an integer) is like %X,
+but takes up at least N (a number) positions.
+The modifiers are `E' and `O'. For certain characters X,
+%EX is a locale's alternative version of %X;
+%OX is like %X, but uses the locale's number symbols.
+
+For example, to produce full ISO 8601 format, use \"%Y-%m-%dT%T%z\".
