B.4. DATE AND TIME
Following function written in C explain how the date and time are coded:
void ExtractDateTime(int date, unsigned int time, int dt[])
{
dt[0] = (time % 30)*2; /* sec */
dt[1] = (time/30) % 60; /* min */
dt[2] = time/1800; /* hour */
dt[3] = date & 0x001F; /* day */
dt[4] = (date>>5) & 0x000F; /* month */
dt[5] = ((date>>9) & 0x007F) + 2000; /* year */
}
