No.

If a human says a recurring meeting happens at 9 AM Pacific time and the following week they are in daylight saving time, it'll still happen at 9 AM local time. Preserving intent is crucial in this case.

Even better with "virtual meetings": 9AM in which user timezone? Sometime people move and they still expect the meeting to happen at 9am for them.

[ttymck]

isn't that a local time and not a timestamp/datetime?

[kelnos]

Sort of. If you expect to have to deal with people in other time zones, though, you still need to carry time zone information, so the person who lives in New York will correctly dial in to the meeting at their noon and not their 9am.

(This also raises the point that you need to preserve zone information, not just the UTC offset. Otherwise the meeting will move after a daylight saving time change, which is not usually what people want.)
