Wrong string for replacement patterns

This original string is wrong:
%m = Day of the month, with leading zeros

%m is not the day of the month, it is the month as a numeric number with leading zeros and the counterpart of %n without leading zeros.

Also I would standardize and order strings for better readability:

• %d = Day of the month, with leading zeros (two-digit)
• %j = Day of the month, without leading zeros
• %m = Representation of the month, with leading zeros (two-digit)
• %n = Representation of the month, without leading zeros
• %Y = Representation of the year (four-digit)
• %y = Representation of the year (two-digit)
• …
• %i = Representation of the minute (two-digit)
• %s = Representation of the second (two-digit)
