Problem Using Toad 11.6 with TFS v 2010

I am getting the following error while running the initial export in the VCS

Error: Unable to add revision from VCS repository. TF203093: You attempted to check in one or more items while specifying an invalid check-in date and time stamp. The date and time stamp is invalid because it is later than the current server date and time:
I have not found any mention of this error number anywhere online.

Does anybody know what the problem here is?

Thanks,
Mendy
