As a result of the Energy Policy Act (2006) , the start and end dates for Daylight Savings Time (DST) are changing in 2007. With this law, DST will start on the second Sunday of March and end on the first Sunday of November.

This document addresses questions regarding the extension of Daylight Savings Time, and the impact on the use of Help/Systems Business Intelligence products Abstract, Esend, Sequel, and Sequel Web Interface.

The simple answer is, none of the Business Intelligence products will be affected by the change in Daylight Savings Time. No settings or preferences within these products need to be changed.


The core of the Abstract product is the cross reference database. None of this data is system date and time sensitive. The change in DST will have no impact on Abstract.


ESEND will reflect the change in DST (in the date/time sent line of the generated email) based on the system value QUTCOFFSET, which specifies the local time offset from Universal Time/ Greenwich Mean Time. DST has no impact on the ESEND email creation or sending process.

Sequel and Sequel Web Interface

Both SEQUEL and SEQUEL Web Interface do not use the system time internally to process data. You can manipulate date and time within SEQUEL queries, but this occurs only when you initiate a SEQUEL process. As a result, SEQUEL and SWI are not dependent on any internal code. They both simply reflect the time that is set on the system.
