While trying to sort this out my daughter pointed out that while we're on daylight saving time , my computer is not recognising this fact as we have started DS time earlier then normal. Her up to date laptop doesnt have this problem.
Just finished checking CdC,I found that my UTC was staying on +10. Checked on my daughters laptop and the UTC auto changes to +11. So like you all said forget daylight saving.
Thanks Gary, just logged in and found your post.
Wasn't aware that CdC adjusted the time for local time according to the co-ordinates.
As bojan said "so if you fiddled with this, there goes your 7 degrees".
But its good to fiddle, make mistakes, etc.
Now hoping for some clear sky to test it all out.

Maybe at Snake infested Valley this saturday.
Thanks again to all

Richard
ps Maybe my next upgrade will be an Argo navis, any comments.
