  Hi Tim:
        The following data structure:
        [[13:22 13:41][14:50 15:04][15:58 16:03][16:53 16:58]]
        Is a nested block or list recognized by the rebol programming
        language. Each value: 13:22, 15:04 etc is a value of datatype "time!"
        and rebol has the ability of easily doing math on such datatypes.
        Regardless of what programming language that I might be working in,
        I use this approach to "pipe" such a data structure to a simple
        application that I have written. That application then returns
        the sum, which is inserted into the buffer. (See my initial post)

        The rebol binary is very easy to install. Small footprint, no
        external libraries are necessary. I would be happy to provide
        the application as well as the elisp code to manipulate it.

        As for the elisp code, I now have a function that grabs the data
        structure and puts it in the kill-ring.

        I now have to ask another question myself, related to this subject.
        I'd like to copy _only_ the text at the car of the kill ring to a
        variable, for further processing use:
        Example:
        alt-: (car kill-ring) => 
        #("[0:58 1:42 0:43 1:41]" 0 20 (fontified t) 20 21 (rear-nonsticky t
        fontified t))
        How I can copy the first item
        "[0:58 1:42 0:43 1:41]"
        from the car of kill-ring into a variable?
        Thanks again
