I just realized there should at least be a warning in
the manual that if Subsurface is used shortly after changing
time zones, dive planning may make significantly wrong
assumptions on the pre-existing tissue saturation of the diver.

The worst-case scenario would be a short trip over the
international date-line, if the diver correctly changes his
locale settings, and plans a dive thereafter that Subsurface
assumes to be in the past of another logged dive he actually
recently did.
