Answers.Body: <p>reading around the subject I think it depends more on if your UK customers are running events across the world. If they aren't, and the events are purely UK based, then I would not expect to see any issues and I don't think the upgrade is critical for events timezones.</p>
  <p>This is just my thoughts from reading around, someone else may have a more background on it.</p>

Answers.Text: If your timezone does not observe daylight saving/summer time, then it might be ok but best to use 5.46 until resolved. A single timezone still has issues if it observes DST.

Answers.Text: But for example Europe/London is different than UTC. Europe/London observes DST, whereas UTC does not. You will have a problem with Europe/X if that zone observes DST. Even if you set the regional settings to UTC, if somebody then in 5.47 creates an event with timezone Europe/London, you will have trouble.

I have several clients using events, but all are in the UK which has a single timezone. I'm assuming the date problem won't affect UK users, but I'd like to check my assumption.  Can anyone help?</p>
