From: erc@khijol.UUCP (Ed Carp, aka Mr. Ed the talking horse...)
Newsgroups: alt.sources
Subject: addtimes - add a list of times in XX:YY form
Message-ID: <1425@khijol.UUCP>
Date: 9 May 90 03:51:43 GMT
/*
*
* This little hack will add times and give you the total. It's handy for
* mixing songs when re-recording a tape, and you want to make sure that the
* songs all fit on the tape.
*
* usage: times time time time ...
*
* times must be in the form XX:YY
*
* Written 04/29/90 by Edwin R. Carp (erc@khijol.UUCP) at 2:30 AM, so don't
* fuss at me for the lack of docs! You can use this for anything you want -
* it's free. If you can make money off of this, hey - more power to you!
