Gradually skewing the clock doesn't exactly work that well if the offset exceeds a few minutes. You don't want to run with a wrong clock for hours or even days.
Maybe ntp, ntpdate etc. should recommend adjtimex?
If, then only ntpdate + adjtimex is a good combination.ntp has its own sophisticated logic if skewing, but does not correct offsets > 500 sec (AFAIK). Having your BIOS clock at local time (e.g. UTC+1), then installing Linux with configuration system clock = UTC, will remain a falseticker. Even offsets of some minutes need a long time to be corrected by ntp.
Chrony can correct hours very fast. Helmut Wollmersdorfer
