3.2 Clock jump procedure
Scenario 1 – Clock moves forward an hour
The weekend the daylight saving will be applied in the night of Saturday on Sunday; the clock will jump
forwards on 01:59:59 to 03:00:00 hours.
Environment

{timecode-offset-sec} {3600} #(UTC+1H)
Main and backup K2 Edge servers are in sync.
A 23 hours schedule is loaded.
A 23 hours continuous schedule is available so the K2 Edge will play out as normal. The only change is
that the clock of the K2 Edge servers should jump with an hour. To maintain continuous playout, this is
done step by step, first the backup and later the main K2 Edge.
Main (at UTC+1) on air
Backup (at UTC+1)  Main (at UTC+1)
Backup (at UTC+2) on air
 Main (at UTC+2) on air
Backup (at UTC+2)
