Afterwards, it is not possible to move back to the TLO as it was before the commit action.
Users have to undo the editing actions in the TLE and to re-commit to the TLO.
Editing actions performed on the TLE and not yet committed can also be canceled by
overwriting the TLE with the TLO.
7.4.2. Committing the TLE
You need to click the button to commit the changes from the TLE to the
TLO.
When the TLO is being played out, only the uncommitted changes located after the TLO
security zone are applied to the TLO.
When the TLO is on pause, the whole TLE is reapplied to the TLO. This commits all
uncommitted changes, without taking into account the security zone.
The following screenshots show the timeline display before and after a commit action.
Before Commit
The TLO is being played out: the TLO nowline is moving forward.
The Remaining Commit Duration extends from 11:00:28:XX to 11:00:49:XX.
After Commit
After committing the changes, the TLE is the same as the TLO. The remaining Commit
Duration is no longer displayed, and all timeline elements have their usual color.
