(PDF 1.5) Meaningful only when the form is being submitted in Forms
Data Format (that is, when both the sfXML and sfHTML flags are
clear). If set, the F entry of the submitted FDF will be a file
specification containing an embedded file stream representing the

The standard date format
PDF defines a standard date format, which closely follows that of the international standard ASN.1
(Abstract Syntax Notation One), defined in ISO/IEC 8824.
A date string is defined as follows:
YYYY is the year
MM is the month
DD is the day (01 -31)
HH is the hour (00 -23)
mm is the minute (00 -59)
SS is the second (00 -59)
O is the relationship of local time to Universal Time (UT), denoted by one of the characters +, -,
or Z (see below)
HH followed by ' is the absolute value of the offset from UT in hours (00 -23)
mm followed by ' is the absolute value of the offset from UT in minutes (00 -59)
The apostrophe character (') after HH and mm is part of the syntax. All fields after the year are
optional. The default values for MM and DD are both 01; all other numerical fields default to zero
values. A plus sign (+) as the value of the O field signifies that local time is later than UT, a minus
sign (-) that local time is earlier than UT, and the letter Z that local time is equal to UT. If no UT
information is specified, the relationship of the specified time to UT is considered to be unknown.
Whether or not the time zone is known, the rest of the date should be specified in local time.
For example, December 23, 2004, at 7:52 PM, U.S. Pacific Standard Time, is represented by the string:
