3  * Simulate an I2C real time clock
10  * This is a test driver. It starts off with the current time of the machine,
11  * but also supports setting the time, using an offset from the current
13  * time-keeping. It does not change the system time.
33  * @base_time:		Base system time when RTC device was bound
34  * @offset:		RTC offset from current system time
35  * @use_system_time:	true to use system time, false to use @base_time
