Should the RTC work as plugin? Or how should it work?

[evilsocket]

if connected, it should just be used to set the correct time on the board, no interaction with the rest of the software is required

I programmed it like this:
I have a script that enables or disables the RTC settings. If you have a clock and disconnect without
configuring it, the system returns to 1970. To prevent this, the script check called by a plugin is done
at startup to see if the clock is connected.
The plugin starts the script at startup and synchronizes the time when the internet is available
Is it good like that?

since there is an optional gps plugin, would it be feasible to acquire the time from the gps?
