Define UserDataSource Type 'Time'

Hi,

How can I define a UserDataSource as 'Time'?

<userdatasources>
  <action type="add">
    <datasource uid="D_C2_Total" type="10" />
    <datasource uid="D_C2_ToWrk" type="10" />
  </action>
</userdatasources>

In this Example UserDataSource is defined as 'Date'.

Thanks! Adrian
