如何判断是英国夏令时 [英] How to tell if it's British Summer Time

问题描述

我有以下代码，应该返回60的偏移量（以表明目前在英国，我们处于英国夏令时-即格林尼治标准时间之前60分钟）：

I have the following code, which should return an offset of 60 (to show that in the UK at present, we are in British Summer Time - ie. 60 minutes ahead of GMT):

var info = TimeZoneInfo.FindSystemTimeZoneById("Greenwich Standard Time");
DateTimeOffset localServerTime = DateTimeOffset.Now;
double off = localServerTime.Offset.TotalMinutes;
return off;

但是，它返回0。

有人可以帮我解决这个问题吗？

Could anyone please help fix this for me?

推荐答案

使用 TimeZoneInfo.IsDaylightSavingTime方法（DateTimeOffset）来查找您的时区当前是否为夏时制。

Use TimeZoneInfo.IsDaylightSavingTime Method (DateTimeOffset) to find if it is currently Daylight saving for your Timezone.

var info = TimeZoneInfo.FindSystemTimeZoneById("Greenwich Standard Time");
DateTimeOffset localServerTime = DateTimeOffset.Now;
bool isDaylightSaving = info.IsDaylightSavingTime(localServerTime);
