This article applies to Microsoft BizTalk Adapter Pack 2010.
Symptoms
Consider the following scenario:
-
You use a receive location to poll data on a Microsoft BizTalk Windows Communication Foundation (WCF)-based SQL adapter.
-
You define a SQL statement in the PolledDataAvailableStatement binding property. Additionally, you define a polling time interval in the PollingIntervalInSeconds binding property.
-
Daylight saving time will end when the SQL statement is running.
In this scenario, the SQL statement stops running for one hour when clocks are rolled back for the end of daylight saving time. For example, you change the time zone of the system to US & Canada Central Time. Then, you change the system time to November 4, 1:58 AM. After two minutes, daylight saving time ends and the system time is rolled back one hour. In this situation, the SQL statement stops running for one hour.
