For those who want to export the raw coding data using different time formats, there is an extension that allows you to add an extra duration column:
▪To specify the required time format, select
General - Program - Settings
▪Switch to the tab Statistics time format:
▪Select the time format of your choice and confirm with OK.
▪Select Additional - Extensions - Functions 
> Time values - Add 'duration' column.
A new (Duration) column is created and for each line, the duration of that Event is inserted.
