 * %A full weekday name; i.e. "Monday"
 * %a abbreviated weekday name; i.e. "Mon"
 * %B full month name; i.e. "June"
 * %b abbreviated month name; i.e. "Jun"
 * %c time and date; i.e. "Mon Jun 18 09:46:17 2007"; same as "%aÊ%bÊ%dÊ%H:%M:%SÊ%Y"
 * %D month, day and year with leading zeros; i.e. "06/18/07"; same as "%m/%d/%y"
 * %d two digit day of the month, 01-31

 * %H hour from 24-hour clock as two digit number, 00-23
 * %I hour from 12-hour clock as two digit number, 01-12
 * %k hour from 24-hour clock, 0-23
 * %l hour from 12-hour clock, 1-12
 * %M minutes as two digit number, 00-59
 * %m month as two digit number, 01-12
 * %O Spanish weekday name; i.e. "lunes"
 * %o abbreviated spanish weekday name; i.e. "lun"
 * %p "AM" or "PM"
 * %Q spanish month name; i.e. "junio"
 * %q abbreviated spanish month name; i.e. "jun"
 * %R hours and minutes separated by colon, uses leading zeros and 24 hour clock; i.e. "09:00" and "21:05"; same as "%H:%M"
 * %r hours:minutes:seconds AM/PM using 12-hour clock and leading zeros; i.e. "09:05:00 AM"; same as "%I:%M:%SÊ%p"
 * %S seconds with leading zeros, 00-59
