Thanks Corinna, this gets me over my hump.  I've used CST6CDT in the past and if I try it
now it doesn't work either, only if I add the '+' or '-' symbol, i.e. CST+6CDT.  It seems to
me that there might still be something wrong on my Cygwin side because things aren't consistent
with Linux.  I can use TZ=America/Chicago, TZ=CST6CDT or TZ=CST+6CDT and they all work on
Linux.  The date command works fine on Cygwin.  Cygwin only seems to work with CST+6CDT syntax
for gawk.  Anyway, thanks for your insite.
