> When converting timestamp/date to string group, {{toString}} is called on {{java.sql.Date}} and {{java.sql.Timestamp}}, which pick up the default time zone to represent the date/time as a String. This can lead to the wrong String representation. See {{ConvertTreeReaderFactory.StringGroupFromTimestampTreeReader}} or {{ConvertTreeReaderFactory.StringGroupFromDateTreeReader}}.
> {{StringGroupFromTimestampTreeReader}} should apply shifting, similar to {{TreeReaderFactory.TimestampTreeReader}}.
> {{StringGroupFromDateTreeReader}} should use a date formatter in UTC.
