Please be more specific. What do you mean by importing terms?

On some webpages there are importing Links for Events: Title, Location, Time of start and end. And these times are changed always one hour later with win10. So my calendar is wrong. With Android it is ok. I hope this helps.

in all probability your windows computer is set to the wrong timezone and as a result is providing daylight savings time or not daylight saving, despite the time in the bottom of the windows toolbar showing correctly.

If you are right with your astimation, for my opinion the problem should be only in some months of the year. But it is always over years. And some of my friends don´t use thunderbird any more, because of that problem.

Did you check your timezone on your windows device, or just post this thought on the topic? I have no idea where you live or how your device is configured. What I do know is that even invitations use UTC time, and unless the timezones are set correctly then incorrect results will appear. The most common of these are related to daylight savings. On the off chance you are from the USA, I see they have multiple timezones one hour apart. Perhaps your setting is not correct and your friends setting are also not correct. Windows defaults from the factory to PST so unless someone actually set the thing correctly everyone on mountain time would have a one hour issue with their calendar entries.

UTC -8 PST Pacific Standard Time UTC -7 MST Mountain Standard Time UTC -6 CST Central Standard Time UTC -5 EST Eastern Standard Timeset

It is also possible the correct timezone is not set in your Thunderbird settings for the calendar. But this is generally picked up from the operating system at install time.
