Your dashboard time clock is good and should be kept in the future.
The only problem I had was to readjust the size of data with S57 charts.
I am still searching for the soundings adjustment.
Your 4.6.2 version is quite correct.
Thanks a lot.
I have submitted the new clock gadgets to Github. Thanks to all who beta tested. Since the upload to Github is complete I am not going to need any more beta testers. Thanks to all who volunteered to help.
