Great, a C question!

There's no FILE * parameter, so how does the function know where to get
the date from?

I'm surprised you don't have a date structure, at least as an
alternative.

There's not enough explanation here.  I don't know what this function
does exactly.  The notation (for exaple N*rg) does not help.

Ah.  I'm not surprised there are bugs, but I'm not going to wade through
this to try to fund any.
