Odd scripting problem.

I wrote a shell script in an attempt to see what's changed in my
repository in the past week. I've had problems passing a date to
svn, though, and have simplified the script down to this:

        #!/bin/ksh
        thetime="2006-12-01"
        svn log -v -r \'{$thetime}\':HEAD

This results in the following output:

        svn: Syntax error in revision argument ''{2006-12-01}':HEAD'

I get this error no matter what shell I try to use. I've tried
escaping the quotes and the curly brackets, and using doublequotes;
all of them result in the same Syntax error. I can echo out that
"svn log" command, then copy-and-paste it on the command line and it
will work perfectly.

Any idea what I'm doing wrong?
