Read the time and convert to a 32 bit value suitable for FAT filesystem timestamps.
Reads the time into internal variable time_store[7], and converts for FAT filesystems.
- Returns:
- uint32_t FAT time encoded in a 32 bit value
See FATFS documentation for the specification of FAT time stamp format time_store must consist of an array of at least 7 bytes A side effect of calling this function is to update the time stores in time_store Format of time_store is (in BCD) ss,mm,hh,date,month,dow,yy
