Have you tested it with Cygwin?
I forgot to append cygwin to th mail address, my answer to Eric from 'yesterday'


----------------------------------------------------------------------------
try
$ date -d yesterday


I am using
$ date --version
date (GNU sh-utils) 1.16

at LINUX and Cygwin W95.
But note the differences:
$ uname -a 
CYGWIN_95-4.0 DAVID 20.1 (0.3/1/1) 1998-12-3 20:39:18 i586 unknown

W95:
$ date; date -d yesterday
Mon Nov 15 18:19:52  1999
Mon Nov 15 18:20:52  1999       # + one minute 
$ date; date -d tomorrow
Mon Nov 15 18:20:01  1999
Mon Nov 15 18:21:01  1999       # + one minute 

LINUX:
$ date; date -d yesterday
Monday 15 of November 18:04:30 CET 1999 KW 46
Sunday 14 of November 18:04:30 CET 1999 KW 45

I hope it's a known error
and not in the newer versiion
