920: Make the StartTime part of RunNode r=Jimbo4350 a=mrBliss
When starting a node, the
nodeStartTime method can be used to obtain the
start time. This method will return the right time for each block type, and
thus protocol. For example, for real Byron blocks, it will extract it from the
Genesis config. For mock blocks, it will just use some hard-coded dummy date,
since the start time is not important for mock blocks.
