SHL: Date and Time Applet
Description:
The Date and Time applet allows you to adjust the date and time of your system. It also allows you to configure your Time Zone and gives you the option to automatically adjust the clock for daylight saving changes. In Windows Vista and higher, you now have the option of adding additional clocks to the standard Date and Time view. Additionally, if your workstation/server is not Domain joined, then you have the option to synchronize the date and time with an Internet time server.
Scoping the Issue:
The most common issues related to the Date and Time applet are as follows:
Date and Time not updating when joined to a Domain : When the computers belong to an Active Directory domain, Windows Time Service configures itself automatically, using Windows Time Service that is available on domain controllers. Windows Time Service configures a domain controller within its domain as a reliable time source and synchronizes itself periodically with this source. These settings can be modified or overwritten, depending on specific needs.
Date and Time not updating when configured for a workgroup : When the computers are part of a workgroup, you must manually configure the time synchronization settings. One or more computers might be identified as a locally reliable time source by configuring Windows Time Service on those computers to use a known accurate time source, either by using special hardware or a time source available on the Internet. Then, all other workgroup computers can be configured manually to synchronize their time with these local time sources.
Daylight Savings Time not changing when it should : Daylight saving time (DST), and "Summer Time" in much of Europe, is the practice of moving local time forward one hour in the spring and backwards in the autumn. These spring and fall shifts to DST are different between northern and southern hemispheres. The start of DST in the northern hemisphere is in March or April (depending on the country/continent), and ending in October or November. In the southern hemisphere, the changes are the opposite, with DST beginning in October and ending in March or April. Generally, DST is not observed in Asia and Africa, and parts of Central and South America.
Unless certain updates are applied to your computer, the time zone settings for your computer's system clock may be incorrect during this four-week period. In particular, you must make sure that both your Windows operating system and your calendar programs are updated.
We strongly recommend that DST and time zone updates be installed on all affected systems, devices and applications to ensure consistency with current DST rules and time zone settings worldwide. Please see the link under Additional Resources that points to the latest Windows cumulative DST update.
Data Gathering:
In all instances, collecting either
MPS Reports
with the General, Internet and Networking, Business Networks and Server Components diagnostics, or a Performance-oriented MSDT manifest must be done.
