    <TEXT>In my former book, Theophilus, I wrote about all that Jesus 
began to do and to teach until the day he was taken up to heaven, 
after giving instructions through the Holy Spirit to the apostles he 
had chosen.</TEXT>

Given the above I would like to calculate the duration of the speech. 

The video is being dubbed and we need to let the translators know how 
many seconds they have to say the equivalent text.

    <START-TIME>02:22:00</START-TIME>
    <END-TIME>2:35:13</END-TIME>

the format is 
minutes:seconds:frames 

where there are 30 frames per second and 60 seconds per minute
The minutes are not consistently padded --- maximum time will be about 
120 minutes -- 

I would like the results to be like:

13.4
Truncated(or rounded if easier) to one decimal place.

BTW this is part of the project I needed to get a list of speakers for 
also.
