JR32707: TIMET_FROM_TIMESTAMP RETURNS INVALID RESULTS FOR DATES < EPOCH.

APAR status

• Closed as program error.

Error description

• Per Jerry Callen:
  
  orchestrate/timestamp/timestamp.C needs several changes:
  
  - factor d1970 constant from the two places it's used and make
  it a static function that initializes the value on first use.
  - the code in asTimeT64 has to cast the result of the julian()
  function to be signed, like this:
  
    APT_Int64 daysSince1970 =
      ((APT_Int64) stampRepPtr->date_.julian()) - ((APT_Int64)
  d1970().julian());
