The S3 archives are currently organized by submission date not (local) collection date. This discussion is probably better to have in person with Mark.

If the splitting of the session at that point is a problem, let me know - i don’t know what the server-side requirements for organisation are.
We do need to split at some point for the 24h submission interval, midnight local time was brought up as a probably convenient cut-time.
What exact time we choose shouldn’t matter too much?
