I am afraid that there are some misleading expressions in this chapter "Supported Date and Time Formats".
eg.
(i) "MM & II" in "Time Formats" express "minutes & seconds" whereas "II & SS" often do the same in other places --- to avoid mistaking "M of minites" for "M of month".
(ii) The Format for "doy" in "Compound Formats" does not allow "000" shown in the Example.
(iii) "M / MM" in Table "Localized Notations" in "Compound Formats" are used for "month" whereas "MM" allows 00-59 according to the Table "Used Symbols".
