What is the difference chronyd and ntpd ?

Specifically interested in the moment with a smooth time adjustment. It is believed that chronyd does not know how. How safe is it to use in production, especially when combined with services that are quite sensitive to time travel (which can be caused by a sharp transfer of hours)? For example, MySQL server may not survive a sharp transfer of time for a few seconds and fall. Which, of course, is unacceptable in the current project.

    Chronyd is still able to! And by default it is this mode and activated. During operation, Chronyd always smoothly adjusts the time if the makestep directive is missing (or a zero limit is specified). However, you can set the number of time adjustments during which the daemon can change the clock readings in steps.
