Edited Issue: Set-SCSMobject unable to set datetime field [8810]

Hi,
 
I wanted to set a dateTime value into the TargetResolutionTime of an incident. This fails always with an error message (see below).
I use the SMLets Beta 3 and SCSM2010 SP1 CU2.
 
Since I'm able to update other fields and I'm sure I used a dateTime value, I guess it is a bug in the SMLets.
But may be I'm wrong. In that case please let me know.
BTW: I also used (Get-Date) to set the dateTime value.
 
Thanks for your help
 
Oliver
