Time creep or time jumps still there

The time of the Linux server and the Domino server differ always (except during a few minutes after reboot). We have read for previous versions of Domino 8.5 that this was called time creep. A fix was promised than for later version, which 8.5 is.

In our case the time can jump from the Domino server. In other words in a few minutes, Domino shows in some cases that it is a few hours later.

We have tried the notes.ini extension: SERVER_TIMESYNC_INTERVAL=1 without result.

Is there any other way to keep the time of Domino equal to the operating system?
