In 8.5, the old (up to 8.4) '''clock scan''' command is deprecated in favour of the new 
'''clock scan -format'''.

This is covered by TIP #173 [http://www.tcl.tk/cgi-bin/tct/tip/173.html], and I understand the reasons behind creating
the new version, but I think it would be a great pity to lose a great usability aid for applications that use dates - an easy way
of letting the user type in "yesterday" or "last week". I may be missing something, but I can't see any way to deal with this in the new version.

I guess what I am really saying is, deprecate it if you like, but don't '''ever''' take the old code out.
