Some pseudo code:
This doesn't work properly presumably due to the signed arithmetic(??)
How do you do this?

repeat

if <somecondition>
now:=cnt

. 'do more stuff
.
if cnt > now + 5*80_000_000
' 5 seconds should have elapsed since <somecondition>

if cnt - now > 5*80_000_000
It's also more reliable to do
if cnt - now > 5 * clkfreq
You may not always run your program with a 80MHz clock.
After reading your reply I realised that·I had used the difference method elsewhere in my code to get·'time between events'.
You say "..works better.." but actually you mean works always.
and yes, I neglected to note in my pseudo code .. "assuming an 80MHz clock.."
Thanks again
