--------------------------------------
Hi Ivan Masár,
allow me to comment on your post.
-- OAICAT
I think the correct way of solving this problem is changing the OAICat
behaviour, using tweaks as solutions isn't a good method. Theoretically (based
on the OAI-PMH protocol) OAICAT behaviour it is not correct. That is, assuming
from=0001-01-01 and/or until=9999-12-31 on the absence of from/until parameters
is not correct. If not defined, they should be considered as it: undefined.
-- ORACLE
The Oracle problem, in fact, is related with the defined timezone.
Look at here:
http://grepcode.com/file/repo1.maven.org/maven2/org.dspace/dspace-api/1.8.2/org/dspace/search/Harvest.java#Harvest.toTimestamp%28java.lang.String%2Cboolean%29
Oracle database should be defined with UTC timezone.
-- Conclusion
OAICAT is working wrong.
There are some ORACLE issues that must be documented in the DSpace manual.
The patch (only) solves the OAICAT problem.
