'now' and other relative values does not work in views filter

drupal version 6.13
php version 5.2.6-1+lenny3
cck version 6.x-1.1
date version 2.4 (tried also latest dev snap)
cache disabled
views cache cleared

Also checked other issues,
there are similar ones,
but they give no clues to me.

Included field export / content copy
and screenshot, which is often helpful.

I have view which I want to filter by date, relative to 'now'.
I tried to insert every kind of relative things as described below the inputfield:

Relative value
Relative values will be used if no date is set above. Use 'now' to default to the current date at runtime or add modifiers like 'now +1 day'. The To date default value is used when the operator is set to 'between' or 'not between'. You can use any values PHP's date_create() can understand, like between '12AM today' and '12AM tomorrow.

I cannot make any of them to work.
Every time I get error 'is invalid'.
(This is second bug not to report field name).

Do I miss something or is this expected...?
