Interesting. Still any backward adjustment however small seems potentially dangerous. I googled a bit and it seems many ntp services can slow down the time until its in sync instead of adjusting it backwards. That seems safer.

Generally it isn't a backward adjustment but simply a slowing down of the clock until the 'real time' catches up. On the other side, you speed up a clock to catch up to the real time rather than catching up all at once.
