This does not solve the problem at all.

The problem is that strftime() in awk is gnu-awk specific. Once you use 
that function, the user has to have gnu awk installed on his system. My 
point is requiring gnu awk is not better than requiring gnu date, so you 
didn't get closer to working on non-gnu systems.

That awk -c or --traditional is only a way that may help you testing your 
awk scripts, to find out that strftime() is a no-go. It does not solve the 
original problem.

Btw, I do agree that removing the need for strftime is a better solution 
(but it's still worth thinking over all the above, for other 
compile-time-dependency cases)
