Subject svn commit: r834310 - /db/derby/docs/trunk/src/ref/rrefdatefunc.dita
Date Tue, 10 Nov 2009 02:31:01 GMT
Author: bpendleton

New Revision: 834310

URL: http://svn.apache.org/viewvc?rev=834310&view=rev
Log:
DERBY-4107: Clarify description of DATE function with integer argument.

This change clarifies the description of the DATE function when it is
given an integer argument. The previous text stated that the DATE function
took the argument as the number of days since the year 0001, but this is
incorrect; the function uses 1970 as the reference year and computes the
number of days since then.

The change also adds an example of the result of DATE(789).
