Trimming ten-thousandths of a second during TIMESPAN conversion to the DateTime
in the NET Provider for Firebird.
-----------------------------------------------------------------------------------------------------------------
Key: DNET-654
URL: http://tracker.firebirdsql.org/browse/DNET-654
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 4.7.0.0
Environment: Windows 10, 64-bit
Reporter: Kamil Kocian
Assignee: Jiri Cincura
The NET Provider for Firebird trims ten-thousandths of a second during TIMESPAN
conversion to the .NET DateTime type in method TypeDecoder.DecodeTime(int
sql_time). Trimming the ten-thousandths of a second is causing problem when
comparing time read from Firebird to .NET and using the value again in SQL
statements.
However it is possible to initialize .NET type DateTime(or TimeSpan) with
number of ticks, this way keeping the precision of Firebird TIMESTAMP in .NET.
Problematic source code in
FirebirdSql.Data.FirebirdClient\Common\TypeDecoder.cs :
public static TimeSpan DecodeTime(int sql_time)
{
int millisInDay = sql_time / 10;
int hour = millisInDay / 3600000;
int minute = (millisInDay - hour * 3600000) / 60000;
int second = (millisInDay - hour * 3600000 - minute * 60000) / 1000;
int millisecond = millisInDay - hour * 3600000 - minute * 60000 -
second * 1000;
return new TimeSpan(0, hour, minute, second, millisecond);
}
