Detailed Description

FAT date representation support Date Format. A FAT directory entry date stamp is a 16-bit field that is basically a date relative to the MS-DOS epoch of 01/01/1980. Here is the format (bit 0 is the LSB of the 16-bit word, bit 15 is the MSB of the 16-bit word):

Bits 0-4: Day of month, valid value range 1-31 inclusive. Bits 5-8: Month of year, 1 = January, valid value range 1-12 inclusive. Bits 9-15: Count of years from 1980, valid value range 0-127 inclusive (1980-2107).
