I've been using
SkyLog Pro for a few months now and I find it pretty good. You can actually download it for free, and then try it for a month. That's more than enough time to be convinced!
It does seem to have been developed Stateside (date entries are made in mm/dd/yyyy format), but it is JAR-compliant. There are many ways to access previously entered info/records, and clever features such as graphs, pie-charts, plus monthly hours calculation/FTLs etc. Data entry is also very quick.
However, I would recommend keeping a classic logbook as a backup - I know I do! Belt and braces and all that...
Cheers
