     "Because the location at the start of the loop is written at the end of the Kernel loop, the last `particle.time` of the particle is not written to file. This is similar behaviour to e.g. `np.arange(start, stop)`, which also doesn't include the `stop` value itself. \n",

-    "If you do want to write the last time to file, you can increase the `runtime` or `endtime` by `dt` (although this may cause a TimeExtrapolationError if your run was to the end of the available hydrodynamic data), or you can call `pfile.write_latest_locations(pset, time=endtime)`. Note that in the latter case, the particle locations (longitude, latitude and depth) will be updated, but other variables will _not_ be updated as the Kernels are not run again."
