如果您居住在美国^(USA)或其他一些可以使用夏令时^{(Daylight Saving Time)}的国家/地区，但发现该设置在您的 Windows 11/10 计算机上不起作用，那么这篇文章将向您展示如何修复它。如果自动调整夏令时^{(Adjust for daylight saving time automatically)}选项在Windows 设置^{(Windows Settings)}面板中显示为灰色，以下是一些可能对您有帮助的故障排除建议。

什么是Windows 11/10中的^(Time)夏令^(Daylight)时设置

夏令时^{(Daylight Saving Time)}或DST是美国和其他一些地区的常见^(United) 做法。^(States)如果在您的 PC 上激活了夏令时选项，您的系统将在夏季将时钟从标准时间提前一小时，并在秋季恢复更改。这样做是为了让用户在此期间可以更好地利用阳光或日光。

与其他一些设备一样，Windows 10也具有此功能。但是，如果它无法在您的 PC 上运行，或者该选项在Windows 设置^{(Windows Settings)}中显示为灰色，您可以在本指南的帮助下修复它。

自动调整^(Adjust)夏令时显示为灰色

要修复Windows 11/10夏令时变灰^{(Daylight Saving Time is grayed out)}错误，请遵循以下建议 -

1. 更改时区
2. 从注册表编辑器启用 DST。

1]更改时区

视窗 11

右键单击^{(Right-click)}任务栏^(Taskbar)上的Windows按钮，然后从选项列表中选择设置。或者，您可以组合按Win+I直接进入设置。

从左侧的侧面板中选择时间和语言设置。^{(Time & language)}

移动到右侧的日期和时间选项卡，然后单击以展开它。^{(Date & time)}

当定向到新屏幕时，找到时区^{(Time zone )}标题并点击它旁边的下拉菜单，然后选择可以使用夏令时^{(Daylight Saving Time)}的不同时区。

视窗 10

如前所述，DST仅在全球少数几个国家/地区可用。因此，您可能需要更改时区，以便 Windows 10 可以启用此功能。

按Win+I打开Windows 设置^{(Windows Settings)}，然后转到时间和语言^{(Time & Language )}设置。确保^(Make)您位于日期和时间^{(Date & time)}选项卡中。如果是这样，您可以展开“时区^{(Time zone)}”下拉菜单，然后选择可以使用夏令时^{(Daylight Saving Time)}的其他时区。

2]从注册表编辑器启用DST

如果如上所述的解决方案对您不起作用，则必须从注册表编辑器^{(Registry Editor)}强制进行调整。为此，在您的 PC 上打开注册表编辑器，然后导航到此路径 -

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation

在您的右侧，您可以找到一个名为DynamicDaylightTimeDisabled的条目。

确保将数据设置为零 (0)^{(zero (0))}。如果没有，您可以设置该特定数据并检查是否启用了DST设置。

如果要强制更新DST调整，可以将Data设置为一 (1)^{(one (1))}。

我希望这对你有用。

夏令^(Daylight) 时^(Savings) 的目的是什么^(Time)？

夏令时^{(Daylight Saving Time)}的唯一目的是通过调整时钟将一小时的日光从早上移动到晚上，从而更好地利用日光。它在夏季进行，因此也称为夏季时间^(Time)。研究^(Research)表明，夏令时^{(Daylight Saving Time)}有助于将整个国家的用电量缩短一小部分但意义重大。

夏令^(Daylight) 时^(Savings) 的规则是什么^(Time)？

美国的夏令时 ( DST ) 时间从每年3 月的第二个^(March)星期日^(Sunday)开始，时钟提前一小时。该过程在11 月的第一个^(November)星期日^(Sunday)DST结束时反转并改回标准时间。

Adjust for daylight saving time automatically is grayed out in Windows

If you live in the USA or some other countries where Daylight Saving Time is available, but find that the setting is not working on your Windows 11/10 computer, then this post will show you is how to fix it. If the Adjust for daylight saving time automatically option is grayed out in the Windows Settings panel, here are some troubleshooting suggestions that might be helpful for you.

What is Daylight Saving Time setting in Windows 11/10

Daylight Saving Time or DST is a common practice in the United States and some other regions. If the Daylight Saving Time option is activated on your PC, your system will forward the clock one hour from standard time in the summer and revert the change in the fall. It does this so that users can utilize the sunlight or daylight better during that period.

Like some other devices, Windows 10 has this feature as well. However, if it is not working on your PC or the option is grayed out in the Windows Settings, you can fix it with the help of this guide.

Adjust for daylight saving time automatically is grayed out

To fix Daylight Saving Time is grayed out error in Windows 11/10, follow these suggestions-

1. Change Time Zone
2. Enable DST from Registry Editor.

1] Change time zone

Windows 11

Right-click the Windows button on the Taskbar and select Settings from the list of options. Alternatively, you can press Win+I in combination to go to the settings directly.

Select Time & language settings from the side panel on the left.

Move to the Date & time tab on the right and click to expand it.

When directed to a new screen, locate the Time zone heading and hit the drop-down menu next to it, and select a different time zone where Daylight Saving Time is available.

Windows 10

As mentioned earlier, DST is available only in a few countries around the world. You may, therefore, need to change the Time Zone so that Windows 10 can enable this functionality.

Press Win+I to open Windows Settings, and go to Time & Language setting. Make sure that you are in the Date & time tab. If so, you can expand the Time zone drop-down menu, and select a different time zone where Daylight Saving Time is available.

2] Enable DST from Registry Editor

If the solution, as mentioned above, is not working for you, you must force the adjustment from Registry Editor. For that, open Registry Editor on your PC, and navigate to this path-

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation

On your right-hand side, you can find an entry called DynamicDaylightTimeDisabled.

Make sure that the Data is set to zero (0). If not, you can set that specific data and check if the DST setting is enabled or not.

If you want to force-update the DST adjustment, you can set the Data to one (1).

I hope this works for you.

What is the purpose of Daylight Savings Time?

The sole purpose of Daylight Saving Time is to make better use of daylight by tweaking the clocks to move an hour of daylight from the morning to the evening. It is done during the summer months and hence, also known as Summer Time. Research suggests Daylight Saving Time helps in cutting short the entire country’s electricity usage by a small but significant amount.

What is the rule for Daylight Savings Time?

The daylight saving time (DST) period in the U.S. kickstarts each year on the second Sunday in March when clocks are set forward by one hour. The process is reversed and changed back to standard time on the first Sunday in November when DST ends.
