- Generic RTC class support. If you say yes here, you will
- be allowed to plug one or more RTCs to your system. You will
- probably want to enable one of more of the interfaces below.
- This driver can also be built as a module. If so, the module
- will be called rtc-class.

- If you say yes here, the system time will be set using
- the value read from the specified RTC device. This is useful
- in order to avoid unnecessary fschk runs.
