This question relates to both mysql in general and the mysql++ C++ API in
particular, thus the adressing to both lists.

I have a DateTime object (really a formatted string) say "2002-07-10
11:38:38". I want to subtract some variable number of hours (from 0 to 11)
from it. How do I accomplish this in an elegant manner?

There is quite a bit of logic to handle all the cases where subtracting
hours takes the date one day back, which can take the month one month back,
which can take the year one year back! And of couse all the months have
different lengths so this can be some ugly code. I can do this the hard way,
but I was wondering if anyone already has a nice solution.

Many thanks

Rich
