The agent jobs are running on an incorrect interval if the customer is using specific scheduled values when the TZ Microsoft Windows environment variable is being used due to changes in Daylight savings in 2007.


If a legacy application is no longer using this environment variable it can be removed, or a hotfix can be downloaded from Microsoft to correct this issue.

The hotfix and additional information can be found at


When using the TZ environment variable, the C Run-Time (CRT) localtime function and the CRT _localtime64 function will not correctly recognize DST. These functions will recognize DST as starting on the first Sunday of April and as ending on the last Sunday of October for all dates.
