Is there an algorithm for solar eclipse duration?

[StephenG1CMZ]

I assume an algorithm for solar eclipse duration exists, but I was surprised it does not appear in Jean Meeus's Astronomical Algorithms (or if it does, its not obvious).

The section on solar eclipses describes types of solar eclipse, but none of the examples give durations.

The only durations appear within the section on lunar eclipses.

I have implemented eclipse calculations here:

(It's in Python, so should be easily ported).

Can anyone suggest sources for solar eclipse durations? (Or where on earth they might be seen?)
