    Even though there is no formal precondition for the upper limmit of value, providing an extremely large number may result in a crash. That can, however, only happen by a programming mistake, as the only meaningful values are those that result in period’s start date not lower than 14 August 1991, the date when arXiv.org was launched.

    Precondition

    value > 0
