From VistApedia
DTFormat(FMDate,format)
;"SCOPE: PUBLIC
;"Purpose: to allow custom formating of fileman dates in to text equivalents
;"Input: FMDate -- this is the date to work on, in Fileman Format
;" format -- a formating string with codes as follows.
;" yy -- 2 digit year
;" yyyy -- 4 digit year
;" m - month number without a leading 0.
;" mm -- 2 digit month number (01-12)
;" mmm - abreviated months (Jan,Feb,Mar etc.)
;" mmmm -- full names of months (January,February,March etc)
;" d -- the number of the day of the month (1-31) without a leading 0
;" dd -- 2 digit number of the day of the month
;" w -- the numeric day of the week (1-7)
;" ww -- abreviated day of week (Mon,Tue,Wed)
;" www -- day of week (Monday,Tuesday,Wednesday)
;" h -- the number of the hour without a leading 0 (1-23) 24-hr clock mode
;" hh -- 2 digit number of the hour. 24-hr clock mode
;" H -- the number of the hour without a leading 0 (1-12) 12-hr clock mode
;" HH -- 2 digit number of the hour. 12-hr clock mode
;" # -- will display 'am' for hours 1-12 and 'pm' for hours 13-24
;" M - the number of minutes with out a leading 0
;" MM -- a 2 digit display of minutes
;" s - the number of seconds without a leading 0
;" ss -- a 2 digit display of number of seconds.
;" allowed punctuation symbols-- ' ' : , / @ .; (space, colon, comma, forward slash, at symbol,semicolon,period)
;" 'text' is included as is, even if it is same as a formatting code
;" Other unexpected text will be ignored
;"
;" If a date value of 0 is found for a code, that code is ignored (except for min/sec)
;"
;" Examples: with FMDate=3050215.183000 (i.e. Feb 5, 2005 @ 18:30 0 sec)
;" "mmmm d,yyyy" --> "February 5,2005"
;" "mm d,yyyy" --> "Feb 5,2005"
;" "'Exactly' H:MM # 'on' mm/dd/yy" --> "Exactly 6:30 pm on 02/05/05"
;" "mm/dd/yyy" --> "02/05/2005"
;"
;"Output: Text of date, as specified by above

; finally, a string within single quotes 'foo' is a separate token.
