You need to use SUBSTR to pick out the various bytes for each element, and
then use UNPACK to convert to a numeric that can be displayed.  The "year"
example was just to show you how to do the first part.  The rest was left
for you to explore.

The SUBSTR transform can be told where to start.  So for example, start at
position 2 for the month, and only one byte:

hrSystemDateMonPacked: SUBSTR : {hrSystemDate} 2 1
hrSystemDateDayPacked: SUBSTR : {hrSystemDate} 3 1

Then you "simply" unpack into integers.  I say "simply" because I don't
really know how to use unpack, and only guessed at the format character
required for the year.  Because year is 2 bytes and month and day are each
1 byte, it's not the same unpack format character.  I had a go at unpacking
the month and day-of-month, but I wasn't able to get it to unpack
correctly.  Once you can crack the unpacking, should work for you.
