Chrony is actually a much more in-depth program than we've discussed here, and we barely mentioned its command-line utility (chronyc), which can be used to make all sorts of changes on the fly.

It's also a good idea to have a think about how you're going to set up an NTP pool, if you find yourself in an environment requiring one. Generally, it's a rule of thumb that you configure multiple potential servers, instead of just one (that might skew or break). Three is better than one or two (two is quite bad, as you don't have an agreement on what the correct time is.)
