C-Map

[Quincofish]

I use C-Map on my lap top for navigation and it works great, except the tide function. It displays that my time zone is GMT -10 hours, my time zone is in fact GMT + 10 hours. The navigation side of C-Map shows this correctly, but the tide does not. Does anyone have any thoughts etc on this?

I think I would send a note to the C-Map people and let them know so they can make the correction. And see if they'll send you a new card. I like them because they have an update and exchange program......................._/)

I don't have a card, this is the C93, software only version, runs on a PC.

It may be that the C-Map version you have uses WTides or some other external tide prediction program. If so, you will need to fire up the separate tide software and change the date in that program. Or, get used to dragging the red timeline marker with your mouse...
