Typically this shouldn't be possible, because the interestAccruedAsOf couldn't be after the current timestamp. However, when assessing we allow this function to be called with a past timestamp, which raises the possibility of overflow. This use of min should not generate incorrect interest calculations, since this function's purpose is just to normalize balances, and handing in a past timestamp will necessarily return zero interest accrued (because zero elapsed time), which is correct.
