In general tide calculations are horribly complicated

YES, this is what make a project like this so dificult and thus so "sexy". A very unusual problem here in the monastery.

but also by the topography of the sea floor in the "local" area

yep ...and don't forget the barometric pressure. The local parameters are important.

A lot of parameters should be in any of the modules managing time/localtime, other groups in modules belonging to Math and Astro categories, and a fourth set should be calculated for the specific area and probably need to be measured in the field. If I could make a wish I will add also a plotting method at the end, (maybe Graphics::Timeline or something equivalent).

Writing a Perl module to perform the required calculations would not be particularly hard

I agree

but the result is likely to be slow

Well this is an advice that I will take seriously. Can I abuse of your time and knowledge and ask you to explore this a little more GrandFather?, do you honestly think that this would be a major obstacle to do this in Perl? (instead i.e. C). Generally speaking of course, how this problem could be avoided? (i.e not choosing a time-module know for being slow etc...)
