Cause of the silly time system LOTRO is using, gametime is the same as your localtime. And is not the same all over Europe. As known, we are working with -1GMT, GMT, GMT+1 and GMT+2.
If you are not sure which zone you belong, you can go to:
http://www.timeanddate.com/worldclock/
and see the current GMT time.
However, I see many of us, use the GMT+2 timezone, like me. And my idea is to use this as the current gametime. Means, everytime I or anyone else (if nothing else is specified) time is reffering to GMT+2.
Example: GB run Tuesday is 07.00pm GMT+2
If you are living in the accurate GMT zone, you will have to log on at 05.00pm
Sorry if this sounds confusing, but I can and will move all the blaming over to Turbine, those geeks who cannot create a decent gametime.
Remember, we are using GMT+2 (= gametime)
