TimeSpan - Interval Mapping Problem -> Error: 22007: invalid syntax for type time: 200.00:00:00

Detailed description
i am using the .Net 4.0 Entity Framework and npgsql

I have a table with an 'interval' field and I have an object which refers to this field as Time in the csdl mapping
file(which basically is a TimeSpan object in c#).

When updating this field, all values up to 23:59:59 are accepted and the SQL looks like this with call_limit as the
DB field:

UPDATE "domain"."gateway" SET "call_limit"=TIME '23:59:59' WHERE "id"=7

Bigger values, like this
UPDATE "domain"."gateway" SET "call_limit"=TIME '24:01:00' WHERE "id"=7
end up in
FEHLER: Datum/Zeit-Feldwert ist außerhalb des gültigen Bereichs: »24:01:00«
LINE 1:"='G-DT-1',"type"='Account',"call_limit"=TIME '24:01:00'...
something like "the value is outside of the valid area" error message.

I also place values like 200 days in my Timespan object, which end up in the following SQL:
UPDATE "domain"."gateway" SET "call_limit"=TIME '200.00:00:00' WHERE "id"=7
This causes the same error as the above one.

I think that this is a database problem which can be avoided by another sql statement like this using implicit casting:
UPDATE "domain"."gateway" SET "call_limit"='23:59:59'::interval WHERE "id"=7
UPDATE "domain"."gateway" SET "call_limit"='24:01:59'::interval WHERE "id"=7
UPDATE "domain"."gateway" SET "call_limit"='200.00:00:00'::interval WHERE

These queries work.

Here are some additional information about the error:

the column type is interval. i'm using the entity framework
to get the objects persisted in the database, so i cannot
(or: will not) write my own sql-queries.
the mapper seems to use TIME instead of INTERVAL when
inserting values, so that it creates an INSERT INTO tbl
(col1) VALUE (TIME '24:01:00'); which in fact throws an
error but INTERVAL '24:01:00' would work.

In my case

select TIME '23:59:59'; --23:59:59
select TIME '24:01:00'; --ERROR: date/time field value out of range: "24:01:00"
select INTERVAL '23:59:59'; --23:59:59
select INTERVAL '24:01:00'; --24:01:00
select version();--"PostgreSQL 9.0.3, compiled by Visual C++ build 1500, 64-bit"

How type of field "call_limit" in table "domain"."gateway"? Interval?
