(snip) I snipped four paragrpahs of lecturing and replaced it with this (snip) :

If you're going to use symbolic constants then USE THEM. Instead of using
'add_mo+7', use 'sec+1'.  It is just much clearer (although not entirely)
when your loop is going to terminate. (It also means that if you get another
GPS that doesn't give yrmsb/lsb for some reason, you can just drop them and
the code will read the CORRECT number of bytes anyway.)

Finally, you can add a parameter to CLOCK to tell it where to start
assigning labels - if you must.
E.g. CBLOCK 0x10 will start with month=0x10, day=0x11 etc.
