Comment(by nickm):

 On further investigation, the culprit code is probably the logic in
 configure_accounting() that resets the accounting period if the start of
 the current accounting period is not the same as what it was before.

 It's not totally clear what to do in this case.  If the start of the
 accounting period moves _back_ in time, then it's probably okay to
 remember the bytes we already wrote.  But what should we do if it moves
 forward in time, yet still overlaps with the previous accounting period?
 (Ignore for now the fact that we don't record when the old period was
 supposed to end.)

 One easy fix would be to add some way to specify that accounting periods
 are to be taken relative to UTC rather than local time, but that leaves
 the major issue unaddressed.
