Insert fields date time

Please, if I do in writter:
insert- fields- time, how canI achieve that it shows in the document the CURRENT TIME, and not only the time I have inserted it?
Many thanks!

Doubleclick on this field and change Time (fixed) to Time
Fixed time

In LO 4.1.2.3 under Windows XP the field inserted when you Insert > Fields > Time is Time (fixed). Which LO version and OS are you using? Maybe that has been fixed/changed?
