British Telecom use hhhh:mm:ss as a time format for length of call in
downloaded accounts. Excel97 does not recognise this as a number so I cannot
reformat to hh:mm:ss. I've tried (with no experience) a macro to remove the 2
leading zeros, but if I set it up by converting the first 10 times, then try
to run it starting at the 11th time, it does not convert the second set of
ten, but simply replicates the times created (for the first ten) when setting
up the macro.
