K2 Edge Version 4.1 Daylight Saving Time (DST) - 5
Scenario 2 – Clock moves backward an hour
The weekend the daylight saving will be applied in the night of Saturday on Sunday; the clock
will jump backwards on 02:59:59 to 02:00:00 hours.
Environment
External LTC given in UTC.
Offset according to region set in
\\IP_K2Edge\delta\nexos-init-params.txt
{timecode-offset-sec} {7200} #(UTC+2H)
Main and backup K2 Edge servers are in sync.
A 25 hours of schedule is loaded.
There is 25 hours of continuous schedule so the K2Edge will playout as normal. The only change is that
the clock of the K2Edge servers should jump an hour. To maintain continuous playout this is done step by
step, first the backup and later the main K2Edge.
Main (at UTC+2) on air
Backup (at UTC+2)  Main (at UTC+2)
Backup (at UTC+1) on air
 Main (at UTC+1) on air
Backup (at UTC+1)
For automation and scheduling, Operators and Schedule Creators should take note of the following:

The playlist should be running on both the main and backup servers and should be perfectly
synced.
