PM15864: INCORRECT FORMAT IN DATE HEADER IN SIPREQUEST

APAR status

• Closed as program error.

Error description

• When using:
  
  sipServletRequest.setHeader("Date", "Mon, "+new
  Date().toGMTString())
  
  Date is in 12 hour format even though the time should be in PM.
  For example, current time is 14:00 but the date parameter is
  displaying 02:00 instead.
  
  Snippet of the code:
  --------------------
  logger.info("date?toGMTString?is:?"+new?Date().toGMTString());
  
  sipServletRequest.setHeader("Date",?
  "Mon,?"+new?Date().toGMTString());
  logger.info(sipServletRequest.toString());
  
  
  Sample output:
  ---------------
  
  date toGMTString is: 16 Mar 2010 12:57:29 GMT
  
  ...
  Max-Forwards: 70
  CSeq: 2 MESSAGE
  Date: Tue, 16 Mar 2010 00:57:29 GMT

Problem summary

• ****************************************************************
  * USERS AFFECTED:  SIP (Session Initiation Protocol) users     *
  *                  of IBM WebSphere Application Server V6.1    *
  *                  and V7.0                                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: SIP Date header field is encoded in     *
  *                      12-hour time format instead of          *
  *                      24-hour time format.                    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The application sets a Date header in a SIP message, using
  the 24-hour clock representation, but when sending out the
  message, it is encoded in 12-hour clock format.
  
  For example, the application calls:
  SipServletMessage.setHeader("Date", "Sat, 13 Nov 2010 23:29:00
  GMT");
  SipServletMessage.send();
  
  And the sent message contains:
  Date: Sat, 13 Nov 2010 11:29:00 GMT
  
  This is a bug in the SIP container, encoding the time value in
  12-hour clock representation. RFC 3261, section 25.1,
  specifies the time value syntax in the range 00:00:00 -
  23:59:59.
  

Problem conclusion

• The bug is fixed in the SIP container code. With this fix, the
  time value in the Date header is encoded in 24-hour clock
  representation.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.5.  Please refer to the Recommended Updates
