Isn't this exactly what the "-w" option to your hwclock does?

The -w option for BusyBox hwclock takes no arguments and simply writes the system clock into the rtc. I needed the ability to load an arbitrary time into hwclock and then load that into the system on the next boot.

Usually, the "-r" option is run at boot time, and the "-w" option is run at shutdown (via init scripts). If your system is set up this way, you could just set the system time and reboot (bit of a sledge-hammer approach, I know - but would do the job)
