Standard Time Transition: Fall 2015

Back to top

The transition from daylight-saving time (DST) to standard time in the U.S. will occur at 02:00:00 ET on Sunday, November 1, 2015.

All ContentDepot® head-end systems are ready-to-go for a normal transition from daylight-saving time (DST) to standard time in the U.S. at 02:00:00 ET on Sunday, November 1, 2015. Here are some notes about the transition and what you need to do to prepare.

Each DST-ST transition has two components:

  • The time change in your local computers
  • Operational considerations

The ContentDepot operates in coordinated universal time (UTC), an absolute standard that does not adjust for DST or summer time. Likewise, the ContentDepot delivers UTC data via Network Time Protocol (NTP) on the satellite channels. Any time zone or DST offsets are applied at end devices -- typically production computers or time-of-day displays synced via NTP.

Fall Time Change

The ContentDepot transition to standard time is very straightforward:

If your local computers have been updated with the latest DST patches, they will step back one hour at 02:00:00 local time on Nov. 1, 2015 (check with your automation/playback system vendor to see if you need to do any special maintenance or procedures to accommodate this transition).

If you use ContentDepot stream programs overnight on Saturdays (including early Sunday morning):

Each producer will generate an extra live program hour to fill the 01:00 EST hour. You do not have to subscribe to this hour; if you are subscribed to a program that starts at 01:00 EDT, you will get the 01:00 EST program automatically.

Program cueing will operate normally in the 01:00 EDT hour and in the 01:00 EST hour for all live programs.

The NPR Breaking News transmission has been extended to be 25 hours long.

If you play ContentDepot file programs overnight, check your program's portal page. In some cases, the producer has generated a special "extra" hour of their program and uploaded it into the "evergreen" slot. Watch for messages from your program producer(s) for more information.

What Else Do You Need to Do?

The most important action you can take is make sure that your local production systems (including time-of-day displays) have the latest updates so that they'll properly step back. You should also check with your automation/playback system vendor to see if there are any special scheduling considerations for your particular installation.

Also, please be aware that your station may receive a Receiver Conflict report for 1:00 AM on the morning of Sunday, Nov. 1. These conflicts are intentional and do not require any action on your part. They are due to the reversion to standard time. The PRSS NOC has made several special, repeat bookings for the hour of 1:00 AM to account for the time change. The result, however, is you may receive a Receiver Conflict Report.
