SAS
The changes in DST will have no effect on how the SAS® System runs. The information about whether SAS is running on Daylight Saving Time or Standard Time comes from the operating system, and that means that your operating systems needs to be patched for this change.

If you have a SAS program that was written to make assumptions about Daylight Saving Time trasitions, that program might have to be changed. Additional information from SAS on this and other topics is available here: (SAS Note SN-V8+-018773)
