Detailed Description

FAT Time Format. A FAT directory entry time stamp is a 16-bit field that has a granularity of 2 seconds. 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: 2-second count, valid value range 0-29 inclusive (0-58 seconds). Bits 5-10: Minutes, valid value range 0-59 inclusive. Bits 11-15: Hours, valid value range 0-23 inclusive.

The valid time range is from Midnight 00:00:00 to 23:59:58.
