F_AGEINSECONDSTHRESHOLDN

Entrypoint ageinsecondsthresholdnull compatible with UTF-8

   Input      TIMESTAMP   (older) date optionally time 1
              TIMESTAMP   (newer) date optionally time 2
              INTEGER     min. value
              INTEGER     min. value is used (0 = no, 1 = yes)
              INTEGER     max. value
              INTEGER     max. value is used (0 = no, 1 = yes)
   Output     INTEGER     difference in (integer) seconds between timestamp 1 and timestamp 2

   Is parameter 4 (use min. value) set to 1, the result is the minimum value of parameter 3.
   Is parameter 6 (use max. value) set to 1, the result is maximum the value of parameter 5.
   For compatibility reasons:
   If date 2 < date 1 the result is negative. The correct result had be 0 than there is no negative age!
   Use F_AGEIN...N or F_...BETWEEN if you don't want a negative age.
