*
* The directive consists of a percent (%) character,

*
* %<flags><width><modifier><conversion>
*
* Flags:
* - don't pad a numerical output.
* _ use spaces for padding.
* 0 use zeros for padding.
* ^ upcase the result string.
* # change case.
* : use colons for %z.
*
* The minimum field width specifies the minimum width.
*
* The modifier is "E" and "O".
* They are ignored.
*
* Format directives:
*
* Date (Year, Month, Day):
* %Y - Year with century (can be negative, 4 digits at least)
* -0001, 0000, 1995, 2009, 14292, etc.
* %C - year / 100 (round down. 20 in 2009)
* %y - year % 100 (00..99)
*
* %m - Month of the year, zero-padded (01..12)
* %_m blank-padded ( 1..12)
* %-m no-padded (1..12)
* %B - The full month name (``January'')
* %^B uppercased (``JANUARY'')
* %b - The abbreviated month name (``Jan'')
* %^b uppercased (``JAN'')
* %h - Equivalent to %b
*
* %d - Day of the month, zero-padded (01..31)
* %-d no-padded (1..31)
* %e - Day of the month, blank-padded ( 1..31)
*
* %j - Day of the year (001..366)
*
* Time (Hour, Minute, Second, Subsecond):
* %H - Hour of the day, 24-hour clock, zero-padded (00..23)
* %k - Hour of the day, 24-hour clock, blank-padded ( 0..23)
* %I - Hour of the day, 12-hour clock, zero-padded (01..12)
* %l - Hour of the day, 12-hour clock, blank-padded ( 1..12)
* %P - Meridian indicator, lowercase (``am'' or ``pm'')
* %p - Meridian indicator, uppercase (``AM'' or ``PM'')
*
* %M - Minute of the hour (00..59)
*
* %S - Second of the minute (00..60)
*
* %L - Millisecond of the second (000..999)
* %N - Fractional seconds digits, default is 9 digits (nanosecond)
* %3N millisecond (3 digits)
* %6N microsecond (6 digits)
* %9N nanosecond (9 digits)
* %12N picosecond (12 digits)
*
* Time zone:
* %z - Time zone as hour and minute offset from UTC (e.g. +0900)
* %:z - hour and minute offset from UTC with a colon (e.g. +09:00)
* %::z - hour, minute and second offset from UTC (e.g. +09:00:00)
* %:::z - hour, minute and second offset from UTC
* (e.g. +09, +09:30, +09:30:30)
* %Z - Time zone abbreviation name
*
* Weekday:
* %A - The full weekday name (``Sunday'')
* %^A uppercased (``SUNDAY'')
* %a - The abbreviated name (``Sun'')
* %^a uppercased (``SUN'')
* %u - Day of the week (Monday is 1, 1..7)
* %w - Day of the week (Sunday is 0, 0..6)
*
* ISO 8601 week-based year and week number:
* The week 1 of YYYY starts with a Monday and includes YYYY-01-04.
* The days in the year before the first week are in the last week of
* the previous year.
* %G - The week-based year
* %g - The last 2 digits of the week-based year (00..99)
* %V - Week number of the week-based year (01..53)
*
* Week number:
* The week 1 of YYYY starts with a Sunday or Monday (according to %U
* or %W). The days in the year before the first week are in week 0.
* %U - Week number of the year. The week starts with Sunday. (00..53)
* %W - Week number of the year. The week starts with Monday. (00..53)
*
* Seconds since the Epoch:
* %s - Number of seconds since 1970-01-01 00:00:00 UTC.
*
* Literal string:
* %n - Newline character (\n)
* %t - Tab character (\t)
* %% - Literal ``%'' character
*
* Combination:
* %c - date and time (%a %b %e %T %Y)
* %D - Date (%m/%d/%y)
* %F - The ISO 8601 date format (%Y-%m-%d)
* %v - VMS date (%e-%b-%Y)
* %x - Same as %D
* %X - Same as %T
* %r - 12-hour time (%I:%M:%S %p)
* %R - 24-hour time (%H:%M)
* %T - 24-hour time (%H:%M:%S)
* %+ - date(1) (%a %b %e %H:%M:%S %Z %Y)
*
* This method is similar to strftime() function defined in ISO C and POSIX.
* Several directives (%a, %A, %b, %B, %c, %p, %r, %x, %X, %E*, %O* and %Z)
* are locale dependent in the function.
* However this method is locale independent.
* So, the result may differ even if a same format string is used in other
* systems such as C.
* It is good practice to avoid %x and %X because there are corresponding
* locale independent representations, %D and %T.
*
* Examples:
*
* d = DateTime.new(2007,11,19,8,37,48,"-06:00")
* #=> #<DateTime: 2007-11-19 08:37:48 -0600 ...>
* d.strftime("Printed on %m/%d/%Y") #=> "Printed on 11/19/2007"
* d.strftime("at %I:%M%p") #=> "at 08:37AM"
