Customer-Impacting Issues 

 

The following table illustrates the spring time change and how the Interactive 
Program Guide (IPG) displays data. Notice that during the spring time change, there 
is a 1:30 a.m. time period and a 3:00 a.m. time period. The 2:00 a.m. and 2:30 a.m. 
time periods are ignored by the operating system.  

 

Time Change 
12 
midnight 

1:00 a.m. 

1:30 a.m. 

3:00 a.m. 

4:00 a.m. 
 

Manual recordings that are scheduled during the time change period may complete 
one hour later than expected. 
Note: Manual recording is the action of setting up a recording through the 
Preferences screen by manually specifying the channel and the start and stop time 
from the IPG. 
Workaround: There is no workaround for this issue. 
Affected Code: All DVR releases 

 

If your site uses split channels to manage video content, the channel transition 
occurs one hour later than expected on the day DST begins. Split channels split as 
designed on the day prior and the day after DST. 
Workaround:  There is no workaround for this issue. 
Affected Code:  SARA 1.60/PowerTV

®

 OS 3.13, HD 1.6.0, Dual Cak 5.2 and later, 

DVR 1.5.2, and DVR 1.4.3a10c and later 

 

Subscribers who have set up a daily parental control to block a specific program 
during the time change period may find that blocking ends one hour early. 
Workaround:  There is no workaround for this issue. 
Affected Code:  All DVR and non-DVR releases
