Let's consult the Squish Developers Kit. This stuff is stored in the message header in the .sqd file.

  The  XMSG  structure  has  the following format:
  [...]
  date_written   SCOMBO    164  Date that the message was written.

  date_arrived   SCOMBO    168  Date that the message was placed in
  [...]
  __ftsc_date    char[20]  218  FTS-0001  compatible date.   Squish
                                applications should not access this
                                field directly.  This field is used
                                exclusively by tossers and scanners
                                for  preserving the  original ASCII
                                message date.   Squish applications
                                should  use  the  binary  dates  in
                                date_written  and  date_arrived  to
                                retrieve the message date.

If a message is exported from the Squish message base and has an non-empty __ftsc_date field, the tosser should use the contents of that field for the date. If the message has been created locally (no __ftsc_date), the tosser uses the date_written field. (SCOMBO is DOS datetime)

 O>>>> Some tosser's dupe checkers might fail ...

 KR> Isn't the MSGID the solution for that problem?

Yes, MSGIDs is very effective in sort out dupes, but not all messages have a MSGID (see your argument below: old software).

hpt does it wrong. I tested it. What else is there to trouble shoot?

not sure this has anything to do with __ftsc_date in the Squish message base.

It only affects systems that use a Squish database and have downlinks that do a %RESCAN. If it's not fixed it will be there forever. If it were fixed, affected systems could be upgraded to a newer hpt version. Just because some sysops are to lazy to use up-to-date software doesn't mean we shouldn't care about bugs and bug fixing.

It's just a simple bug ...
