tMyStartTime = DATETIME() &&store the DATETIME() result ? TYPE('tMyStartTime') && should be T - a time variable tEndTime = tMyStartTime + 100000 && equivalent to waiting 100,000 seconds ? TYPE('tEndTime') && also T - another time variable nResultInSecs = tEndTime - tMyStartTime && I'll bet it's 100,000! ? TYPE('nResultInSecs') && it's an N - numeric ? nResultInSecs/3600 && should be 27.7778
