[H-GEN] time in C/C++

I am writing a small financial programme (using graphapp as a Linux replacement
for VB...its not that GUI user friendly but it is quite neat just the same).
The programme is an implementation of the RBA formula for pricing a bond.

The most difficult part of the process is calculating the days between two
dates so its not exactly a major taxing of the intellect.

My query is to asak what people think about the best way of getting the time
between dates. Originally, I thought to use difftime() but I believe that this
method can lead to errors under some circumstances.

The whole process is simple , even if the formula is not (it is a fairly
complex formula but once the individual parameters are known it is just a case
of substituting values).

For safety's sake I thought I would just write my own function as the price of
the bond is critically dependent on getting the date differences right.

Anyone want to offer an opinion.
