May be it makes sense to set "-ncv" as a default behavior of rdate, but there is should be a way to synchronize time without running a demon (don't understand why are people so aggressive about that) if you don't need up-to-second synchronization (in my case modern hardware goes less than a second off per day, and really old hardware - less than 10 seconds).
You don't understand the implications of changing the time of a computer at runtime. Time can be seen a continuum whos axis can be stretched or compressed or as series of time units with fixed length. In the first case the computer clock runs faster or slower, but no time unit is lost. In the second case the computer runs at constant speed, but time units can be lost. If either case is acceptable depends on the software that runs on the computer. A computer that controls an insulin pump probably should run at constant speed whereas a computer that does a task at a certain time should not skip time units. If a cronjob runs at 17:10 and at 17:00 your wise cronjob sets the time to 17:20, cron will not start that job. See?
