patch 8.0.0149: :earlier does not work after reading the undo file

Browse Source 
Problem:    ":earlier" and ":later" do not work after startup or reading the
            undo file.
Solution:   Use absolute time stamps instead of relative to the Vim start
            time. (Christian Brabandt, Pavel Juhas, closes #1300, closes
            #1254)
