Yes!  When I worked out painfully that awk script on the SVLUG mailing
list, a couple of years back, someone immediately pointed out the messy
edge-case problems involving day boundaries.  At that time, I basically
said 'You're right, but I'm quitting here because this is good enough
for intended purposes.'

Perl is almost certainly a better language for such things, as famously
awk runs out of power in a lot of areas where Perl excels.  It happened
that the GNU awk date functions were handy and have a good reputation --
and also that I'm good at awk/sed and totally suck at Perl.  ;->

I can also say with at least a little pride that my sed/awk scripts 
tend to be pretty easy to study and understand, IMO.
