We always try to reply, although it can take a day or 2 sometimes, since we're volunteers, not people paid to be standing by 24x7.
This is probably a timezone issue. There are 2 different places where time zones can be wrong. One is in the database. Some databases will convert dates that are stored into a preferred timezone which is usually either the local timezone or Universal Time (UTC). The other place where timezones can go wrong is in the datetime converter in JSF. Unless you explicitly say otherwise, the default timezone for a date in JSF will always be UTC.
So, in short, it's likely you're not literally off by a day, just a fraction of a day. When it's 22:50 my local time (EST), it's already 03:50 UTC the next day. Give or take an hour. I never can get it right on the first try.
