Following a standard "quick start", I get this output:

    result += int(component) * pow(60, idx + starting_exp)
ValueError: invalid literal for int() with base 10: '7-00'**

I assume this is assuming an HH:MM:SS format (which I prefer too!)

Actually.. I think I found this in the configuration. But would it be a terrible idea to write code to recognize a format?

Sorry guys; that came out wrong. I meant to ask if it would be difficult to write a little pattern detection script. Obviously, not tough in principle, but they can cause conflicts, or make things not break when they should break.
