Technical Reference: 
2012 Fall Time Change Reminder 
Overview 
 
Purpose 
The schedule for the seasonal time change varies in different parts of the world. In 
the United States, the time change from Daylight Saving Time (DST) to standard 
time occurs at 2:00 a.m. on the first Sunday in November (November 4, 2012). This 
technical reference serves the following purposes: 
 
Reminds you of the fall time change for 2012  
 
Describes customer-impacting issues that may occur during the time change 
period as they relate to DVR and non-DVR software running on our digital 
set-tops 
Important:  This is the final DST time-change notice that Cisco plans to issue for 
SARA software. System operators should expect no notice for the 2013 time 
changes. 
Affected Releases 
The contents of this document apply to all SARA DVR and non-DVR releases. 
Important Recommendations 
Cisco urges system operators to heed these important DST-related 
recommendations: 
 
Inspect the DST Rules window upon receiving this bulletin and confirm that 
your settings have not changed. 
 
Do not upgrade client code, starting a week before the time change, until after 
the time change period has passed. 
 
Inspect the Interactive Program Guide (IPG) grid at any time after November 
1, 2012 and confirm that two 1 a.m. entries exist for November 4. Call Cisco 
Services if you do not see the double 1 a.m. entry.
