Jerry, The problem is that Time_Of is in local time. The UK was on daylight saving time on 1st Jan 1970, and so my reference is 1 hour out. Most time zones with no DST in operation will give the correct value. I'd overlook this possibility when I first wrote the C version. That's why we had to

Andrew, On my machine, in Ada example 29, the line xmin := Long_Float(Time_Of(2005, 12, 1, 0.0) - Time_Of(1970, 1, 1, 0.0)); calculates a value of xmin of 1.1333952000E+09 which is the same number that you hard-coded the value to recently. Does your machine not calculate this same
