Have you tested the daylight saving with current DM4? My data seems to
indicate that I do not need to do the one hour subtract for winter months.
However, your DB seems to require that at least for dives done in 2011. (My
own data only has dives on Jan 2013 so it does not really tell much about
the time handling, but contradicts to the -1 hour for winter.)
