英文:
Google calendar api saves dates as UTC and not local
问题
以下是翻译好的部分：
我正在开发一个带有API的应用程序，通过该API，您可以在Google日历中创建事件。我遇到的问题是事件的日期（已正确添加）不是使用我的时区（布鲁塞尔），而是使用UTC。
所以，如果我想在我的时区中创建一个8:45的事件，它会保存为我的日历中的6:45。
这是我目前的代码：
var reservation = new Event
{
Summary = GenerateReservationSummary(reservationInput, selectedCares),
Start = new EventDateTime
{
DateTimeDateTimeOffset = reservationInput.ReservationDate,
TimeZone = TimeZone // 字符串设置为"Europe/Brussels"
},
End = new EventDateTime
{
DateTimeDateTimeOffset = GetEndDateTime(reservationInput.ReservationDate, selectedCares),
TimeZone = TimeZone
},
Reminders = null // 没有提醒
};
在调试时，我能够确保ReservationDate实际上设置为8:45，这确实是情况，并且DateTimeKind也设置为Local。
我尝试了多种方法，如下所示，但没有一种方法有效。
new DateTimeOffset(date, TimeSpan.FromHours(2))
new DateTimeOffset(date, TimeZoneInfo.Local.GetUtcOffset(date))
我错过了什么？
另外，我使用一个带有表单的Angular前端应用程序，该表单发送到API，我在我的Angular组件中有正确的日期，但在API调用负载中以UTC发送。如何修复我的问题（前端或后端）？
谢谢！
英文:
I am developing an app with an API, via which you can create an event in a google calendar. The issue I have is that the date of the event (which is correctly added) is not using my Timzone (Brussels) but UTC.
So if I want to create an event at 8:45 in my Timzone, it's saved as 6:45 in my calendar.
This is the code I actually have :
var reservation = new Event
{
Summary = GenerateReservationSummary(reservationInput, selectedCares),
Start = new EventDateTime
{
DateTimeDateTimeOffset = reservationInput.ReservationDate,
TimeZone = TimeZone // string set as "Europe/Brussels"
},
End = new EventDateTime
{
DateTimeDateTimeOffset = GetEndDateTime(reservationInput.ReservationDate, selectedCares),
TimeZone = TimeZone
},
Reminders = null // No reminders
};
When debugging, I was able to ensure that the ReservationDate was actually set at 8:45, which is the case, and DateTimeKind is also set at Local.
I tried multiple things such as the followings, but none of them worked.
new DateTimeOffset(date, TimeSpan.FromHours(2))
new DateTimeOffset(date, TimeZoneInfo.Local.GetUtcOffset(date))
What am I missing ?
Also, I use an Angular front-end app with the form that is sent to the API, and I have the right date in my angular component, but it is sent as UTC in the api call payload. What's the best way to fix my issue (front or back) ?
Thanks !

默认情况下，事件的时间使用日历本身的时区。
因此，在创建事件时设置时区会让事情变得有点混淆。
英文:
By default the time of an event uses the timezone of the calendar itself.
So by setting the timezone when you create the event you tend to end up confusing things a little.
