Yes, of course:-) [*] The .TIME pseudo variable will give you the current time
in the POSIX meaning (seconds since the Epoch). This may be used to embedd
"best before" dates your code:
.if .time > $3FC4AF1F
.error "This code may not be used later than 2003-11-26"
.endif

This is an advantage when using an assembler without a linker: At least the
ld65 linker cannot change the code size in the linking stage. However, for the
VIC, the useful start addresses do all have less than 5 digits, so at least in
this case it's not really an advantage:-)
