The only sensible start for any time axis is clearly Modified Julian Day 0 which puts the x=0 of any truly god fearing years axis in November 1858, as it should! Alternatively Fermi Mission Elapsed Time is also an acceptably cool zero point, which puts the zero in January 2001. The zero of the unix time is tolerable only in truly desperate circumstances.
