Not at all:

1) $ri Date::strptime

--------------------------------------------------------- Date::strptime
     Date::strptime(str='-4712-01-01', fmt='%F', sg=ITALY)
------------------------------------------------------------------------
     Create a new Date object by parsing from a String according to a
     specified format.

     +str+ is a String holding a date representation. +fmt+ is the
     format that the date is in. See date/format.rb for details on
     supported formats.

     The default +str+ is '-4712-01-01', and the default +fmt+ is '%F',
     which means Year-Month-Day_of_Month. This gives Julian Day Number
     day 0.

     +sg+ specifies the Day of Calendar Reform.

     An ArgumentError will be raised if +str+ cannot be parsed.
-----------------------------

Good luck finding and then digging through the **source code** of 
format.rb to locate anything on the format specifiers.


2) $ri Date#strftime

---------------------------------------------------------- Date#strftime
     strftime(fmt='%F')
------------------------------------------------------------------------
     (no description...)



And from the official Standard Library Documentation for 'date':

1)
strptime(str='-4712-01-01', fmt='%F', sg=ITALY)
----------------------------------------

Create a new Date object by parsing from a String according to a 
specified format.

str is a String holding a date representation. fmt is the format that 
the date is in. See date/format.rb for details on supported formats.

The default str is ’-4712-01-01’, and the default fmt is ’%F’, which 
means Year-Month-Day_of_Month. This gives Julian Day Number day 0.

sg specifies the Day of Calendar Reform.

An ArgumentError will be raised if str cannot be parsed.
=================


2)
strftime(fmt='%F')
--------------
[Source]

That last one is a real doozy--and quite typical of ruby Standard 
Library documentation.
