The current Ada example 29 code has
xmin := 1133395200.0;
(no underscores), and yes, that hard-coded value gives identical results t
Andrew,
Does the Ada example, with xmin hardcoded to 1_133_395_200.0,
generate the same Postscript as the C example? (I can't test this on
my machine because the C example doesn't work correctly, as I
discussed earlier.)

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 ch
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 val
