Workspace PL/I Compilers

Created on Dec 19, 2013

Date/Times before 1582

All Date/Time routines (BIF) should support Date/Times below 15. October 1582 (day one in Lilian).
So, the values (Lilian format) have to support minus numbers (seconds and days).
The low limit may be '0001-01-01' as in DB2.

PL/I have to support the same date/time range as DB2.

    Ok. Our customers can life with only "low-value" (0001-01-01) support.

    I don't think that a date before 1900 is really necessary; therefor I vote for a solution which accepts 01.01.0001 as "low-value".

    adding support for the DB2 low value would be clearly good, but are other dates before Lilian day one really needed? (we're awaiting a reply from this customer)
