Andrus Adamchik closed CAY-1003.
--------------------------------
Resolution: Fixed
Fix Version/s: 3.0
fixed. Indeed this was a problem when explicit caching was used
> the paged queries in ROP can fail to fetch the subsequent pages if the client
> and server are in different timezones

> Key: CAY-1003
> URL: https://issues.apache.org/cayenne/browse/CAY-1003
> Project: Cayenne
> Issue Type: Bug
> Components: Cayenne Core Library
> Affects Versions: 3.0
> Environment: ROP, paging, LOCAL_CACHE with no setCacheGroups
> specified , cayenne v.3.0-SNAPSHOT Mar 05 2008 22:29:23, multiple timezones
> Reporter: Marcin Skladaniec
> Assignee: Andrus Adamchik
> Fix For: 3.0

>
> if the client and server are in different timezone and the executed query has
> an qualifier like this:
> ExpressionFactory.greaterOrEqualExp(CourseClass.ENDDATETIME_PROPERTY, new
> Date())
> there is a possibility of a mismatch between the keys identifying the cache.
> What happens I believe is that the initial SelectQuery creates the key on
> server, using the server timezone, while the query which faults the following
> page of data creates the key on client. My assumptions are based on the
> exception we see when we are trying to connect across timezones (we are in
> EST, server is in WST):
