Adding a unit test that shows how time_extrapolation errors are hard to read

Error on this unit test is
Particle P[0](lon=25.000000, lat=-35.000000, depth=0.000000,
time=3218745600.000000)[xi=40, yi=20, zi=0]
Time time: 3218745600.000000,   timestep size: 300.000000
Field sampled outside time domain at time 3218745600.000000. Try
setting allow_time_extrapolation to True

That large number is very difficult to read. Field.time_origin should
be used to convert this number into a readable format
