Start - Predecessor activity with a finish milestone

Hi,

I have the following problem in P6:

I have assigned activity A with a finish mile stone, finishing on 01st March 10 08:01 AM (08:01 AM is the time appearing in the finish column0 .
Activity B having a duration of 03 days with activity A as the predecessor & FS relationship shows start date as 01st March 10 08:01 AM & finsh date as 04-Mar-10 08:01 AM. Is’nt this wrong.

In fact the correct finish date for activity A must be 01st March 10 06:00 PM & for activity B start date as 02nd March 10 08:00 AM & finsh date as 04-Mar-10 06:00 PM.
How do i get this right in P6.

Cheers,

Richu
