ah sorry, when I was debugging I changed the endianness.

  0x9B530150 -> 0x5001539B ->
  01(year_1) 010000(flags) 00(hour_2) 000001(minute) 01010(day) 011(hour_1) 1001(year_2) 1011(month)
  month 1011 -> 11
  year  01 1001 -> 25
  day = 01010 -> 10
  hour = 011 00 -> 12
  minute = 000001 -> 1


 with no endianness change should be: 

 1001(year_2) 1011(month) 01010(day) 01100(hour) 000001(minute) 01(year_1) 010000(flags)

 with your data:

 1001(year_2) 1011(month) 01010(day) 01011 (hour) 000011(minute) 01(year_1) 010000(flags)
 
 16+9=25       11            10        11              3
