clock scan

Hello,

today is Wednesday the 30.01.2008.

% clock format [clock scan "Monday last Week"] -format "%d.%m.%Y"
28.01.2008

?? shouldn't it be 21.01.2008


% clock format [clock scan "Monday next Week"] -format "%d.%m.%Y"
11.02.2008

?? shouldn't ist be 04.02.2008

% clock format [clock scan "Monday this Week"] -format "%d.%m.%Y"
unable to convert date-time string "Monday this Week"

?? shouldn't ist be 28.01.2008


How do i get the date of Sunday/Monday/Tuesday.. in the actual Week?


Thanks,
Matthias
