First computer with real-time clock?

The 650 does not have such a feature inherently, so now I'm trying to determine if there was ever an adjunct product that IBM produced to give the 650 the ability to tell time. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
