MatrixRun should use the same timestamp so that SCM can check out the same ws for all configurations.
This breaks some of the UI (in some sense) --- for example, the web page would report that the build started 15 mins ago, when in fact it hasn't been sitting in the queue for the most of the time.
The build duration is still computed correctly.
