Sorry, SGI's man page doesn't mention any limitations.

R's or SGI's? The limitation seems to be on SGI only, and I've sent privately some suggestions. Windows has (had before I fixed the code) the same problem, but then Microsoft didn't exist in 1970 (although Bill Gates did, so he must have problems with his date of birth). -- Brian D.
