27.10Beware sys$bintim behaviour on OpenVMS AlphaXDELTA::HOFFMANSteve, OpenVMS EngineeringFri Jan 31 1997 13:0615
   One of the more interesting Y2K related problems is the apparently
   not (fully) documented sys$bintim behaviour on OpenVMS Alpha -- it
   accepts either a two or a four digit year.

   This can lead to some differences in (potentially degenerate)
   application behaviour between OpenVMS VAX and OpenVMS Alpha,
   particularly around code that uses sys$bintim to check the format
   of the time.  (Which is what one would expect to have happen -- one
   otherwise needs to implement the code to check the syntax of a time
   string in the application.)

   This has already resulted in differences of behaviour of at least
   two OpenVMS components on the two platforms.

So this means that Digital have upgraded the OS to take into account the
revised standards (ECMA-13 edition 4) without updating their
documentation? Is the upgrade 'official'?
