## 9 Year 2000 Issues

Primordial (but not current) versions of the genuine SCCS suite fail to work correctly in and after the year 2000. The commands affected are `get` and `prs`. Unix vendors have ensured that the version of SCCS that they currently ship works correctly in the year 2000. Sun Microsystems, for example, state in their Year 2000 FAQ (http://www.sun.com/y2000/faq.html)

> • Does Sun see any problems with the source code control system (SCCS)?
> No, Sun has adopted the X/Open Commands and Utilities Issue 5 standard, the year 2000 compliant version of SCCS will not be affected by the end of century transition. The X/Open standard states that old dates held in ("yy/mm/dd") format does not change in “s.” files, but the values “yy” which range from 69 – 99 are to be interpreted as 1969 – 1999 respectively. Values of “yy” which range from 00 – 68 are to be interpreted as 2000 – 2068 respectively. This interpretation ensures that the year 2000 compliant version of SCCS will work at least to the year 2068. By implementing X/Open’s standard, Sun has ensured SCCS user’s compatibility with other providers of the SCCS utility.
