The JSF specification requires that f:convertDateTime:
* interpret the input Date object as being in UTC (this is part of the
spec for java.util.Date)
* map the timezone of the input Date object using the specified
timeZone (or UTC if none specified)
I suspect the problem with your program is in fact that when you load
dates from the database they are being treated as belonging to some
specific timezone, and are being adjusted to UTC (which would be
correct, as java.util.Date should hold a UTC value). Then the
f:convertDateTime has no timezone set, so is writing them out *without*
adjusting them in any way.
The myfaces sandbox project provides an "s:convertDateTime" that always
assumes that timeZone is the localhost timezone rather than UTC. That's
not really very nice, as it only works when a server is limited to users
from one timezone. But if that is your scenario then it might save a
little bit of typing. A very little bit.
