Hi

In rtc_set_time, mktime is called to calculate seconds since 1970/01/01, 
input parameters of mktime are required to be in normal date format. 
Such as: year=1980, mon=12, day=31, hour=23, min=59, sec=59. However, 
the current input parameter of mktime is tm->tm_year, and it is the 
number of years since 1900. (For example, if current time is 2012/12/31, 
and tm->tm_year is 112). This is not suitable for requirement of mktime. 
So I think tm->tm_year should be changed to tm->tm_year+1900 when 
calling mktime. Please check the patch attached.

Thanks,
Annie
