Also, there is already a replacement for ntpdate, it's in the sntp
package.

> b. A default installation of Fedora 18/19, has no means of updating the RTC correctly if it's off by more than 15 minutes; and 60 minutes with newer kernels. An RTC wrong by more than an hour, e.g. two months ago, if I have an internet connection chrony sets the system clock to the correct date/time. If I don't have an internet connection, I'm relegated to a system time based on the wrong RTC, which seems grossly broken to me. 

It was fixed in kernel 3.10, which should be in f19 soon.

> d. This long bug, 816752, suggests, as a solution, installing ntpdate in order to set the RTC. So if ntpdate is being deprecated as part of the proposed feature, why is installing and using ntpdate being suggested as a fix for the lack of chrony-kernel RTC sync support?

Which functionality exactly? Both ntpd and chronyd (in default
configuration) let the kernel sync the RTC.
