29. Warranty relating to future.

Unless otherwise expressly stated, a warranty1 only relates to facts as they are at the time of sale2. It may, however, expressly relate to the future, as where the seller undertakes to deliver horses sound at the end of a fortnight3; but 'warranted sound for one month' has been held to mean not that the horse was warranted to continue sound for a month, but that the duration of the warranty was limited to one month, and that complaint of unsoundness must be made within one month of sale
