Changing the format of time codes

[Sharon]

Apologies if this has already been covered - Is there a way to change time code formats so it shows as 00:00:00 and not the default format?  I am working on some long documents.  One has to be time coded every few minutes and I'm having to change it manually.

Many thanks in advance...

Found it!   For anyone else who needs to know:  Go to Options, Display and select 'Time elapsed'.  In both 'Time format' and 'Duration' select "hh.mm.ss (with leading zero)".

Worked first time!
