First of all there is no specific date issued by IBM , but this what I know ...fresher boy :) A facility that ran on top of OS/360 in the '60s was ASP (which morphed into JES3 in the early 70s) which also supported multi-system processing. While HASP didn't have similar facilities, it was added to it when it morphed into JES2 also in the early to mid-70s.
So it clearly says that the base technology used by JES3 i.e. ASP ,which originated in 60's , so JES3 is the older one .
