vmsdate problem

[C. Harkes]

Dear Readers,

O/S       :  Alpha VAX/VMS version V6.2-1H3
Powerhouse     : 7.10G1

I would like to fill a vmsdate temporary in qdesign by using a date field
temp and a time field temp.
Is it possible ? If I can do this I can easier calculate timedifferences
using the decimaltime function

simplified not working example  :

     screen x

     temp t_time num*6 initial 1030
     temp t_date date initial 20020301
     temp t_datetime vmsdate initial t_date + t_time


TIA
