Hello, HDBC uses System.Locale.iso8601DateFormat to produce format strings for Data.Time.parseTime. This function has been changed with old-locale-1.0.0.2, and HDBC-postgresql now produce conversion errors when dealing with datetime values. The following patch has introduced that regression: Wed Sep 24 21:37:55 CEST 2008 magnus@therning.org * Adding 'T' to conform better to standard This is based on information found at http://en.wikipedia.org/wiki/ISO_8601#Combined_date_and_time_representations I wonder if other packages are similarly effect? How do we deal with that? Just fix HDBC? Regards, Simon
