2015-06-11PcAtChipsetPkg/PcRtc: Fix a Y2K bugRuiyu Ni
The original driver cannot handle the case when system time runs from 1999/12/31 23:59:59 to 2000/1/1 0:0:0. A simple test to set system time to 1999/12/31 23:59:59 can expose this bug. The patch limits the driver to only support year in 100 range and decide the century value based on the supporting range: Century either equals to PcdMinimalYear / 100 or equals to PcdMinimalYear / 100 + 1. The patch passed the Y2K test. However with year range [1998, 2097], when system time is 2097/12/31 23:59:59, the next second system time will become 1998/1/1 0:0:0. I think it's a acceptable limitation.
