This is because of my dodgy sleeping patterns. I updated yesterdays journal at close to midnight (GMT+0), so it falls in the 27th. Todays journal entry will be arriving at about 6:00am, GMT+0.
[edit: better make that 6, not 5....]
I will have screenshots by then, I hope. Preliminary tests don't show anything promising but I have 3 hours. Working under pressure is the way forward, for a chronic procrastinator like myself.
