SYMPTOMS
The start dates and the end dates for daylight saving time (DST) in many countries change from year to year. Additionally, some countries may change their DST recognition policy or may change the local time offset from Coordinated Universal Time (UTC). In this scenario, some schedules and some applications that depend on date and time calculations may have a problem.
CAUSE
This issue occurs because of incorrect or missing time zone information, which can occur if the latest Windows Daylight Saving Time Cumulative Update has not been applied.
RESOLUTION
To fix this problem, follow these steps.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
