The binary time code shows minute 0x064631A = 6578970 of the century. Dividing by 1440 minutes per day, this is minute 1050 (= 17×60 + 30) of day 4568 of the century. There are 365×12 + 3 = 4383 days in the 12 years before 2012, so this is day 185 of the year. This day number begins at 0 on January 1, rather than 1 like the BCD time code, so it encodes the same date.
