End of day would make sense but I am told that the defrost time is 10:30 'til 12:00; the tricky thing is that I don't know whether they use the 24 hour clock or not.

Also, being a harbourside fish market they could be unloading at anytime day or night. A suggested time to me was 00:01 hrs to 01:00 hrs. Anyway it's the first call tomorrow so we'll see what's happening. If nothing else, we'll keep the harbour master happy by turning up.
