Sara Billey: Hello, I don't understand the complaint about the date format.  Could you give an example in the internal format?  I did copy this format from the internal format of an existing sequence, so I am not able to correct this.

15:35

Andrew Howroyd: The date is good now (to my eyes). The system normally puts in the date by itself. It would have been Jul 09 2024 (with an extra 0 - some editors have very keen eyes that instantly spot even the slightest deviations)
