Calendar math problems

[Ben Logan]

Hi,

I need to be able to add/subtract an arbitrary number of days to/from
an arbitrary date.  The days and dates are all within the range
1970-2038, so I thought I would convert everything to Unix time
stamps, do the addition/subtraction on integers, and convert the
result back to a date tuple.

Is this the best way to accomplish the task?  How would one go about
it if the dates fall outside the timestamp range?  I looked at the
calendar module functions, and they would be helpful for writing an
algorithm to do the dirty work, but I don't see any really easy
solution.

Thanks,
Ben
