Larry Stone commented on DS-393:
--------------------------------
The problem is in the usage of the DCDate utils class. The old version was
broken, it gave wrong answers for either GMT or local time, I forget which, but
it was pretty egregious, so I cleaned up the code a lot and fixed it -- there's
now a main() with some test functions so you can observe that the functions at
least perform as documented.
Unfortunately, some existing code had grown bugs to compensate for DCDate's
bugs. I thought I got them, but apparently the fix I put in only works west of
Greenwich.. Here's how it *should* work:
- The submission UI accepts and displays (i.e. for current values to be
changed) local time
- Timestamps in metadata are GMT (ISO 8601 format) so they are interpreted the
same if an Item migrates or gets copied between sites
- DCdate assembles components of a timestamp into a "date" object, filling in
empty month, day, time, etc. Those can be interpreted as either GMT or local
time, so the UI should be accepting local time
So it looks like there is a disagreement between
org.dspace.submit.step.DescribeStep, which parses input values as components of
local time, and org.dspace.app.xmlui.aspect.submission.submit.DescribeStep,
which parses out the GMT values of a date from a metadata value to initialize
UI forms. It ought to be checked in the JSPUI too.
It's actually working fine for us here in GMT-5:00, so that may have masked a
problem. I'll look into it if I have time, but if you can try messing around
with this code, please do.

> Components: DSpace API, XMLUI
> Affects Versions: 1.6.0
> Reporter: Ben Bosman
> Priority: Critical
>
> Each time the describe page containing the issue date field is rendered, the
> date is being reduced by one. This will e.g. occur when adding authors,
> moving back and forth between different steps. This is probably related to
> time-zones.
> Issue experienced on a server with GMT+1
