Hi,
going deeper i found the following:
http://hackage.haskell.org/packages/archive/haskelldb-hdbc/2.1.0/doc/html/sr...
HaskellDB is converting from SqlTimestampT (no timezone defined) to
CalendarTimeT (timezone required). This conversion tries then to be done
using LocalTime (
http://hackage.haskell.org/packages/archive/HDBC/2.2.6.1/doc/html/src/Databa...
)
which fails.
I believe real problem is CalendarTimeT. SqlTimestampT clearly doesn't
define a timezone. There's a need to create a new type to handle these
types. Timestamps but no timezone (Localtime).
I attach a patch for this. I tested this in a project. Not quite sure how
to add the tests. What should i do to add this patch to haskell? A version
dependency of this two should be added,

Hi,
I get
*** Exception: Convertible: error converting source data SqlLocalTime 2012-04-27 10:22:15 of type SqlValue to type Data.Time.LocalTime.LocalTime.ZonedTime: incompatible types
when i try to show a record with a field of type CalendarTime (automatically generated by Database.HaskellDB.DBDirect, Mysql database type is "timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP"
I already looked forhttp:// haskell.1045720.n5.nabble.com/programmatic-DB-interface-td3120759.html. But the problem there is about a regexp (not a type). And the incompatible type problem was caused because of a concatenation. Here, as you can see, i have no idea what's going on.
Can someone please help me?
