From my legacy code:

/** see Freeciv/common/game.c - game_next_year() */
int calculateFreeCivTurns () {

  int turns = 0;

/* this updated formula is the one giving me the bigest headache */
/* add a +1 to this formula to be more accurate */
/* this formula calculate the no. of turn between any two freeciv years (>= -4000)
*/
/* -4000 <= x < -1000, 50 turns */
  turns =  Math.abs ( (Math.min (Math.max (startYear,-4000), -999)
           - Math.min (Math.max (endYear,  -4000), -999)) / 50);

  /** -1000 <= x < -1, 25 turns */
  turns += Math.abs ( (Math.min (Math.max (startYear,-1000),   -1)
           - Math.min (Math.max (endYear,  -1000),   -1)) / 25);

  /** 0 <= x < 1000, 20 turns */
  turns += Math.abs ( (Math.min (Math.max (startYear,    0),  999)
           - Math.min (Math.max (endYear,      0),  999)) / 20);

  /** 1000 <= x < 1500, 10 turns */
  turns += Math.abs ( (Math.min (Math.max (startYear, 1000), 1499)
           - Math.min (Math.max (endYear,   1000), 1499)) / 10);

  /** 1500 <= x < 1750, 5 turns */
  turns += Math.abs ( (Math.min (Math.max (startYear, 1500), 1749)
           - Math.min (Math.max (endYear,   1500), 1749)) / 5);

  /** 1750 <= x < 1900, 2 turns */
  turns += Math.abs ( (Math.min (Math.max (startYear, 1750), 1899)
           - Math.min (Math.max (endYear,   1750), 1899)) / 2);

  /** 1900 <= x, 1 turn */
  turns += Math.abs ( (Math.max (startYear, 1900) - Math.max (endYear, 1900)) / 1);

  return (turns+1);
}

Yes, the above above code didn't take into account of the spaceship parts. I think
we had to change freeciv report.c to include add some header.
